'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(:).'

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(:))

What if C accumarray([A+1, B+1], 1); but C gave the error that:
Error using accumarray Maximum variable size allowed by the program is exceeded.
but I need to have 'C(:)' for scatter3? How would I try to condense this variable?

C = accumarray([A+1, B+1], 1);
