Dear All

I would need some help on this:

I have the following string list:

AAA

ABB

CDE

ABB

CCR

AAA

FDR

I would need to count the different strings in this list which is, in this example 5, and this would be my output.

The acual list may have undreds of strings.

Many thanks in advance!

Hi, use

str    = {'AAA','ABB','CDE','ABB','CCR','AAA','FDR'};
numstr = numel(unique(str))

This is useful. I want a frequency plot of each unique string - any ideas?

str = {'AAA','ABB','CDE','ABB','CCR','AAA','FDR'};

histogram(categorical(str))
