Help with MATLAB basics

I'm new to MATLAB so I'm having some trouble here. Can anyone tell me how to find a specific element in a list? something like the in operator for python. Thanks :)

This is a Matlab forum. Although it is likely, that you find someone who speaks Matlab and Python, it is more likely, that you get a fast answer, if you explain in words, what the program should do.

Answer 1

Most likely you want:

index = find(strcmp(list, element), 1);

if list is a cell string, or:

index = find(list == element, 1);

if list is a numerical vector.

Or, if the "target" number is a floating point number, see the FAQ:

% instead of a == b
% use:
areEssentiallyEqual = abs(a-b) < tol
% for some small value of tol relative to a and b
% perhaps defined using eps(a) and/or eps(b)
theElementIndex = find(areEssentiallyEqual);

or you might want to use ismember(), which is useful in certain cases.

First I should to point you to various get-started documentation...

Then I'd suggest that you read the documentation of:

find
strfind
findstr
isequal
