Hello,
I have a vector A[-3:0.003:3] and a vector B whose values corresponding to those of A. I plotted B as a function of A ( it shows a curve like a gaussian). I would like now to plot in 3D using mesh. From vector A, i have to use two vectors x and y and I have to find a matrix from vector B.
Any help and I thank you in advance!
Adam

Sounds like MESHGRID or NDGRID is what you want.

Hello, Thank you for your answer. But you didn't understand my question.
- I create two vectors x and y from the vector A provided that A=x.^2+y.^2.
- I have to create a matrix C from the vector B.
In this case i can plot mesh(x,y,C)
Thank you!
