Hello guys.

I have a multiple choice question that I want to generate several different responses or answers for in Matlab, but I am very new with Matlab and don't know how to go about it.

For example. I can put the answers to the question in a cell array such as:

>> Answer = {'a' 'b' 'c' 'd'};

But I don't know how to randomly sample or select an answer from this Cell array. I tried to use rand() but it didn't work because it is only for numeric variables.

Is there anything like that for characters or string variables in Matlab?

I want to generate multiple responses so I can find out how much times a particular choice was made, then use that to create a frequency table or some sort of data analysis.
