Counting values in array

[Oficmajster]

Hi, I believe it is clear as sky but I can't manage to solve it.

I have an 2D array filled with random numbers. I need to create an 1D array representing the frequency of appearance of those numbers.

For example: my 2D array has number from 1 to 100, and I want to check how many times the number 25 appears. I need my 1D array to show this value under the index of 25.

Thanks a lot 🙂

You're looking for histogram functions in Mathematics->Prob&Stat pallete.

Oh, and Reshape Array from Programming->Array, to change your 2d array into 1d array 😉

Thanks, it worked fine and dandy 🙂
