MATLAB: How to create matrices from a meshgrid function

3d plotsplotplotting

'The scatter3 plot needs vectors, not matrices, but you can do that easily enough by using meshgrid to create the matrices and then creating vectors from them as RA(:), DEC(:) and A(:).'

Best Answer

a=1:0.1:10
b=1:0.1:10
[A,B]=meshgrid(a,b)
C=sin(A).*cos(B)   % Example
scatter3(A(:),B(:),C(:))
