## How do I make a 3D animation of a matrix plot?...

I am using matrices to input data in order to plot it on a surface plot. Is it then possible to export an animation of this graph rotating around an axis?

My matrix is 40 x 3 Matrix

Thanks :)

## Labeling in matrixplot...

Hello,

I have use a sparsematrixplot to identify the patterns in a matrix.

In order to facilitate the readability of my sparsematrixplot, i would like to change the labels of the rows/ columns axis.

- for my rows, the labels : [eq1,eq2, ..., ]
- for my columns, the labels : [q1,q2,q3,...,]

Do you have ideas how I can do that ?

## intersection of a plane and a matrixplot surface...

How would one plot the intersection of the surface z=3.5 and the surface described by a matrixplot

Here is an arbitrary matrixplot surface for an example.

matrixplot([[3, 4, 5, 1, 1, 1, 2, 3, 2, 1, 7, 8], [2, 3, 4, 1, 2, 1, 2, 1, 2, 1, 2, 5], [7, 8, 7, 6, 7, 8, 4, 5, 3, 2, 1, 2], [2, 1, 2, 4, 5, 6, 5, 6, 7, 6, 5, 6], [2, 3, 2, 4, 5, 4, 5, 6, 7, 6, 5, 4], [9, 8, 7, 8, 9, 8, 9, 8, 7, 8, 9, 8], [9, 8, 7, 8, 8, 8, 7, 8, 6, 8, 7, 6]]);

## Change of axis by matrixplot...

Good afternoon everybody,

I have a question regarding the command matrixplot. I wrote a programm with two input parameters:

v=[seq(0.29+i/100,i=1..8)]

k=[seq(2*i,i=1..50)]*0.5*10^(-15)

and I get a matrix [8x50] that I want plot.

The problem with matrixplot is that I get in the axis the number of rows and columns but I would like to put the value of v and k instead of the row/column's number. Someone knows how I can change that?

## plotting faster intensity levels in an image...

Is there another way to plot 3d intensity levels in an image?  Using matrixplot takes a long time.

## error in matrix command...

my code is almost done but in the end my matrix command is not getting values from array command due to which am not able to get my solution and graph. Am attaching worksheet please let me know how to recorrect it. Thanks

## Graphing parametric sweep results of a MapleSim mo...

Hi,

I'm running a 2D parameter sweep from Maple 15 on a MapleSim 5 model. The output is stored in a 2D matrix.  I've encountered two problems:

1) when I graph it with matrixplot the z-axis values are fine but I can't figure out how to change the x-axis and y-axis values from the matrix indices to the actual values of the swept parameters.

2) When the parameter sweep begins I get a warning about storing the values in a matrix.  Maple...

## Ignore data in matrix when using plots[matrixplot]...

Hello all,

I have been able to plot data points onto a surface using plots[matrixplot]. I would like to display a circular geometry with changes in magnitude in the Z-axis. For Example if I had the following matrix:

0 0 1 1 0 0

0 1 1 1 1 0

0 1 2 2 1 0

0 1 1 1 1 0

0 0 1 1 0 0

I would like  the zero elements to be ignored in the plot as they are not defined.

I was hoping I could provide a special character (such as NULL...

I want to wrap a 3d matrixplot histogram around the surface of a cylinder.  How can I do that?

If my matrix is a random 12x12 matrix and I use heights=histogram to plot it

restart;gc();
