cols#
Purpose#
Returns the number of columns in a matrix.
Format#
- n_cols = cols(x)#
- Parameters:
x (NxK matrix or sparse matrix)
- Returns:
n_cols (scalar) – number of columns in x.
Examples#
// Create a 100x3 matrix of uniform random numbers
x = rndu(100, 3);
// Find out how many columns are in 'x'
n_cols = cols(x);
After the code above:
n_cols = 3
Remarks#
Use getorders() to return both the number of rows and columns in one call.
If x is an empty matrix, rows(x) and cols(x) both return 0.
