Hi,
I'm relatively new to Matlab because I only used Excel so far. For my project I used the COUNTIFS function and I'm wondering how to do this in Matlab.
Say I've got a column vector 300×1:
I want to create a vector of the same size that counts and sums up each entry.
Example:
If my entries are A;A;B;A;B;B;C;A;C the new vector should look like: 1;2;1;3;2;3;1;4;2
Thank you so much!
