There's no such thing as the 'bool' function in base Matlab

% A bool function means it returns to either true or false based on condition statement
if k==c % Condition statement
True statement;
else
False Statement
end

Is it not better avoid a 'bool function', and instead to say
some_variable = (k==c);
then some_variable will be true or false.
Otherwise we're just saying
if true return true; else return false;end
btw how d'you get that neat coloured text into a post?

"Is it not better avoid a 'bool function'..."
Yes
"how d'you get that neat coloured text into a post?"
By formatting the text as code (look above the comment box for formatting options).

Sorry, I see we don't have a boolean data type, and we get a matrix of 1s or zeros.
So a function is useful, but should maybe contain just the one line
return (k==c)(1);
"...we don't have a boolean data type, and we get a matrix of 1s or zeros."
Actually MATLAB has a logical type (displayed as 1s and 0s):
"So a function is useful..."
I don't see why. I would just write the logical comparison in my code.
"...but should maybe contain just the one line return (k==c)(1);"
That looks like a mixture of Python and MATLAB code (the keyword return does not return values in MATLAB, so that line performs some operations, discards any results, and then exits the function).

There is no bool in MATLAB or Simulink. There is boolean in Simulink, which is not recommended https://www.mathworks.com/matlabcentral/answers/375074-erro-using-boolean-with-matlab-on-window-machine#answer_298242
The only place that bool appears in Mathworks related code is in some of the interfaces for generated C++ code.
