delte all rows with zeros from a matrix in matlab

To delete all rows with zeros from a matrix in Matlab, you can use the following code:

main.m
% Example matrix
mat = [1 2 3; 
       0 0 0; 
       4 5 6; 
       0 7 0];

% Find rows with all zeros
rowsToDelete = all(mat == 0, 2);

% Delete rows with all zeros
mat(rowsToDelete, :) = [];
195 chars
12 lines

This code first finds the rows with all zeros using the all function and the logical operator ==. Then it deletes those rows using matlab indexing.

Note that this code assumes that the matrix contains only numeric values and not NaN or Inf values. If NaN or Inf values are present, you can modify the code to check for those as well.
