Hi All,

I have a question that I see has been seldom discussed except certain posts by Mr. Lopez. This concerns the estimation of optimum parameters of the solution of a system of differential equations to fit experimental data. I referred to the Maple document provided by Mr. Lopez on the Maplesoft website.

## Output pdsolve solution as csv or text...

Maple

Hi,

How to output the solution given by pdsolve as a *.csv or a tab delimited text file?

Maple has got to really work on its help documentation.

Thank you,

Hi,

I wish to declare the diffusion coefficient in the Fick's diffusion law as constant and solve numerically.How do I declare constants for a pd to use in pdsolve?I also have some constants in my boundary conditions.

## Command Line difficulties...

Maple

Hello,

this is the first time I am using the command line for Maple.I have a few questions,

1. How do I change my current directory?

I tried with currentdir() but with no success.If my dir is E:\Work ,how do I change it?

2. How to execute a *.mpl?

I tried cmaple.exe <*.mpl> but again no success.

I am using Maple13 by the way.

Any help is golden.

Best regards

## How to see solutions after pdsolve?...

Maple

Hello,

I have solved a system of partial diff. equations with ind. variables (x,t) with two dependent variables.After solving I get something like this,

> solu := pdsolve({eq1, eq2}, ibc, numeric, time = t, range = 0 .. .5, spacestep = 1/2560, timestep = 1/180);
module () local INFO; export plot, plot3d, animate, value, settings; option
