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!

It seems like a homework. What did you try?

randi is a little bit easier.

在 MATLAB Online 中打开

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));
