why the following for loop returns me only the last value? my wish is that the for loop to take the values ​​line by line and not just the last one

Use break statement in the else part of _if_loop and see what result you get

Hi,

Since Corners variable is a matrix, length is probably not the correct function to get the number of elements in particular dimension, you may probably use size. As for the query about last value, I understand that it signifies that only last value in Cornersforcycle is equal to 1. If that is the case, then it is totally dependent on the if condition in the for loop to set the value.

If that doesn’t help, as Vasishta mentioned you can print the intermediate values using disp or can use breakpoints.
