I have a matrix consisting of 512 rows and 512 columns. I have written this matrix down into a text file. Each cell of the matrix contains a positive value. I want to plot these values in 3 dimensional system to form a surface by uploading the text file. How to do it in sage ?
Thank you
Hello,
First you have to load the matrix into sage. It really depends on how did you save the values. To open a file you use the function open from Python.
Secondly, given a matrix, I am not sure there is a ready made solution inside Sage. But you might use point3d. I would think that the best solution is to use directly matplotlib (which is what Sage uses in background). You can have a look at these matplotlib examples.

There is something ready to use
sage: m = matrix(QQ,10,10,lambda i,j : i**2+j**2)
sage: list_plot3d(m)Asked: 10 years ago
