hi,

I would like help with 2 questions regarding complex plots and Euler's formula:

- I'm trying to plot a complex (simple) plot in Maple Flow (2024.2) but got into a problem:

does anyone would know how to fix/solve it?

- how could an complex exponential function be expanded with Euler's formula

Thanks very much in advance.

Hi,

I would like help on accessing an element of matrix which is itself  an element of another matrix, like:

how could I reference the element "1.0" or "6.0"?

Thanks in advance for any help.

I tried the latest Maple flow upgrade (2024.2) and noticed some strange behavior. When I enter units such as L/min or m/s^2, the program states: "invalid unit(s) Units:-Simple:-*" However, to my surprise, if I start the canvas by stating with(Units) everything works as it should. In the user manual however it is stated that the with() commands do not work within Flow. If someone would be so kind to explain what I am doing wrong.

With Maple Flow, we’re regularly rolling out exciting updates. Each offers new features, as well as resolving many user-reported issues.

Flow 2024.2 lives up to that track record. Two major new features - drop-down menus and phasors - make their debut. We've also made many other quality-of-life enhancements.

Drop-down list boxes make your worksheets more tactile and interactive. The menu items can be defined in a matrix or vector, or in a table. You can return the index of the selected item, or return an entire row or column of a matrix.

An important use case is populating the contents of a drop-down menu with data from an external file. In movie below, we

• import a database of steel shapes and their associated properties
• populate the drop-down menu with the steel shapes in the first column of the imported data
• based upon the selected shape, use ArrayTools:-Lookup to return a property
• and finally perform a design analysis.

If you look carefully, you'll see that you can hide commands on a per-container basis to make your worksheets cleaner.

We have a large number of power system engineers who want to model electrical systems in phasor notation.

Entering a phasor is easy - just enter the magnitude, the angle character and then the angle. Phasors evaluate to rectangular complex numbers but can be recast to phasor format with the Context Panel.

You can also associate a unit with the magnitude and angle. On output, you can change units inline or via the Context Panel.

You can also prevent floating point approximation of phasors using the symbolic toggle on each container.

We've also made a raft of other improvements. Extracting slices of matrices is faster, and you can now enter units in 2d notation in the Context Panel (particularly useful when you want to change the units of everything inside a matrix).

As ever, the new features are driven by you. The only way you can point us the right direction is by telling us what you want. Don't be shy!

Hi,

I've just got interested in MapleFlow (and downloaded the trial). I looked at the previous post but I have seen very little activity for MapleFlow. Is it still alive?

Best regards,

Hi,
I'm trying some number theory functions and got a problem with prime factorization.

When I try the function ifactor in Maple, it works perfectly, but when I try it in MapleFlow, I get:

ifactor(50) = 50

Is there something I'm missing?

Thanks in advance for any help.

Hi,

I just got 2 questions regarding symbols and answers in MapleFlow (I might be doing something wrong here).

- In trying to input the integral int(F(x), x = -pi/5 .. pi/5) - this is just an example! - as a symbol,

MapleFlow doesn´t accept fractions or multiplications for bondaries values, unless I input "int(F(x), x = -pi/5 .. pi/5 =". Is there anyway to do it?

- is it possible to have the answer as , like in Maple, instead of ()symbolic expression) or 1.18 (numeric expression)?

Thanks in advance for your help.

We've just launched Maple Flow 2024!

You're in the driving seat with Maple Flow - each new feature has a straight-line connection to a user-driven demand to work faster and more efficiently.

Head on over here for a rundown of everything that's new, but I thought I'd share my personal highlights here.

If your result contains a large vector or matrix, you can now scroll to see more data. You can also change the size of the matrix to view more or fewer rows and columns.

You can resize rows and columns if they're too large or small, and selectively enable row and column headers.

If the vector or matrix in your result contains a unit, you can now rescale units with the Context Panel (for the entire matrix) or inline (for individual entries).

A few releases ago, we introduced the Variables palette to help you keep track of all the user-defined parameters at point of the grid cursor.

You can now insert variables into the worksheet from the Variables palette. Just double-click on the appropriate name.

Maple Flow already features command completion - just type the first few letters of a command, and a list of potential completions appears. Just pick the completion you need with a quick tap of the Tab key.

We've supercharged this feature to give potential arguments for many popular functions. Type a function name followed by an opening bracket, and a list appears.

In case you've missed it, the argument completion list also features (when they make sense) user-defined variables.

You can now link to different parts of the same worksheet. This can be used to create a table of contents that lets you jump to different parts of larger worksheets.

This page lists everything that's new in the current release, and all the prior releases. You might notice that we have three releases a year, each featuring many user-requested items. Let me know what you want to see next - you might not have to wait that long!
