It seems much more clearer that be asked; but I could not find it by my first searches.
Does anyone know how to find size of an array in Mupad session of Matlab?
M := [12 , 21, 432]:
size(M):
length(M):
None of them works well for me.
The command is nops(M) in mupad
EDIT: my bad I wasn't able to get it at first attempt, but I accidentally came across the proper method to obtain what OP asked for. The method is:
linalg::matdim(A)
From manual:
linalg::matdim(A) returns the dimension of the matrix A, i.e., the number of rows and columns of A.
