delete a row in an array if it contains 0 in matlab

To delete a row in an array if it contains a 0 in MATLAB, you can use logical indexing along with the ~ (logical NOT) operator.

Here is an example of how to do it:

main.m
% Example array
A = [1 2 3; 4 0 6; 7 8 9; 10 11 12];

% Find the rows that contain a 0
rowsToDelete = any(A == 0, 2);

% Delete the rows
A(rowsToDelete, :) = [];

% Display the modified array
A
194 chars
12 lines

This will delete all rows in the array A that contain at least one 0. The result will be displayed in the command window.

Note that this method assumes you want to delete entire rows. If you want to delete individual elements containing 0 instead, you can use linear indexing instead of logical indexing.
