boolean condition on array to string in matlab

To convert an array of boolean values to a string in MATLAB, you can use the num2str function to convert the boolean values to a numeric array, and then use the char function to convert the numeric array to a string.

Here's an example:

main.m
% create a boolean array
boolArray = [true, false, true, true];

% convert to a numeric array
numArray = double(boolArray);

% apply a boolean condition (e.g., greater than 0.5)
conditionArray = numArray > 0.5;

% convert to a string
stringArray = char('TRUE' * conditionArray + 'FALSE' * ~conditionArray)

% output:
% stringArray =
% TRUEFALSETRUETRUE
353 chars
16 lines

In this example, the num2str function is not used because double is used to convert the boolean array to a numeric array. Instead, a boolean condition is applied directly to the numeric array to create a new boolean array, and then the char function is used to convert the boolean array to a string by multiplying each element by 'TRUE' or 'FALSE'.
