convert boolean condition on array to string in matlab

To convert a boolean condition on an array to a string in MATLAB, you can use the num2str function along with logical indexing. Here's an example code that demonstrates this:

main.m
% create an example array and boolean condition
arr = [1, 2, 3, 4, 5];
bool_cond = arr > 2;

% use logical indexing and num2str to convert the condition to string
str_cond = num2str(bool_cond);

% display the result
disp(str_cond);
232 chars
10 lines

In this example, the bool_cond variable is a boolean condition that checks whether each element in the arr array is greater than 2. When we use num2str on this condition, it converts the boolean values to 0s and 1s, and then concatenates them into a single string. The resulting str_cond variable is a string representation of the boolean condition.

Note that if you want to convert the values in the arr array to a string instead, you can simply use num2str(arr) without any boolean indexing.
