Hi, i have a matrix, that i set up it will have 200 integer values. i also have a vector of 200 values. i want that each matrix cell will get the value of the vector, for example if cell (200,345) has a value of 20, then it will get the value of the 20th cell of the LUT vector. i know i can do it by double loop, but my matrix is very big and it will take a lot of time, i was wondering if there is a faster solution for the problem. thanks

Use your matrix as index to LUT:
Mnew = LUT(M);

Hi Thorsten, i am not familiar with LUT function, and i don't seem to have it in my matlab version (2014a). or did i misunderstood you.

Hi TZ, LUT is not a function. It is your vector with the 200 values. And M is your matrix.
