Please how  can I use getdata to extract only 200x2 of 208x2 matrix from maple to excel.

For instance I have:

Q:= ( seq( seq( plottools:-getdata(ans1[s1,3])[j,3],j=1..3), s1=1));

It returns  208x2,  200x2 200x2 matrices and I can't extract it using 

`<|>`( seq( seq( plottools:-getdata(ans1[s1,3])[j,3],j=1..3), s1=1));

because the matrices have different dimension. Please, how can make 208x2 matrix to 200x2?

Hi, please how do I delete only the 0*I of the complex expression: 0.*I - 3?

I tried this:  remove(`=`, [0.*I-3, 5, 7, -2], 0.*I);

But couldn't work.

Please, how do I generate a list of ones in maple?

I want to change the colors of a contour such that the region above zero is represented by a different color instead of yellow color,  and that the colors for conts <0 are one set of colors (maybe yellow to red), and the area for which conts >0 is one color which is very different from the others (so maybe white).

Hi 

I wanna export data from maple to excel and I tried this:

ExcelTools:-Export(op([1, 1], plots:-display( convert( ans1[12..14,3], list))));

I was expecting 4 columns including z vector and 3 columns from ans1[12..14,3] but got only 2 columns.Case1_Revised_080922.mw

Please any help?
