Question

I have a problem in MATLAB. I have a NxM logical array called L but if I do dim(L) I get:

Undefined function or method 'dim' for input arguments of type 'logical'

size doesn’t work either. length works but gives me only the number of columns and not the rows.
The weird thing is that in the Matlab workspace it is correctly shown as an NxM logical array.

Does anyone know how I can get the amount of rows and columns of a logical array?

Thanks in advance.

If you want both the number of rows and colums, size is your best choice:

[nRows,nCols] = size(L)

If this fails, use clear size first, since you may accidentially have a variable of the same name in your workspace.
