MATLAB: Random Generator with known characters

Question

I have a list of known character names Cat, Dog, Goose…etc. These names need to be randomly set into a matrix size 20 x 1

Would look like :

[Cat, Dog, Dog, Goose,Cat,..]

How would one go about using rand to create a matrix such as this.

Thank you!

Answer 1

Use randperm() or randi() One of those resamples without replacement while the other resamples with replacement (I'll let you read through the documentation to decide which is best).

c = {'cat','dog','goose','rhesis macaque','mongoose'};
cr = c(randperm(numel(c)));
% or
cr = c(randi(numel(c),1,20));
