create an empty matrix in matlab

To create an empty matrix in Matlab, you can use the zeros() function. The zeros() function creates a matrix filled with zeros. You can specify the size of the matrix using the following syntax:

main.m
matrix = zeros(rows,columns);
30 chars
2 lines

For example, to create an empty 3x3 matrix:

main.m
matrix = zeros(3,3);
21 chars
2 lines

Alternatively, you can use the ones() function to create a matrix filled with ones, or the empty() function to create an empty array.

main.m
matrix = ones(3,3);
empty_array = empty();
43 chars
3 lines

Note that the empty() function does not fill the array with any values. The resulting array is just a placeholder with the specified size.
