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

b:=convert(ToGrayscale(a),Array):
c:=convert(b,Matrix):

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...

### Matrixplot - options

November 10 2012 by Maple
I'm using matrixplot to plot a matrix 10X10.
But I want it to be shown only the interval between column 2..6 and row 1..10.I tried to:matrixplot(M, row = 1..10, column = 2..6, heights = histogram, axes = boxed)
But gave error!

***I can not reset the Matrix for 10x5.Tanks

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...

### How can I wrap a 3d matrixplot histogram...

April 13 2011 by

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();
a:=Matrix(12,12,rand(1..20))
