MATLAB: What type of data (200 x 200 x 200)

Question

I have a data whose size is 200 x 200 x 200 double (seen in the workspace). What type of data is it? is it a matrix or a vector?

Answer 1

It's an array. A 3d array to be precise, but just an array.

A vector (as defined by isvector(...) )is an nx1 or 1xn array

A matrix (as defined by ismatrix(...) ) is an nxm 2d array (so a vector is a subset of a matrix as a 1d array is not possible in Matlab).

You can also specify a row or column vector explicitly with isrow(...) and iscolumn(...)
