How to extract a specific range of values from a multi dimensional matrix?

Hi,

I have a double matrix with the following dimensions: 37 X 745 X 32. This matrix contains many zeros and also quite a lot of values between the range 100-999.9. I would like to extract data values which are in a specific range (ex: 815.6 - 816.4) from this matrix, in order to generate a kernel estimation plot. Can anyone please help me here, as I am unable to figure out how to do it?

The values lose their matrix identity and return as a column vector, but ‘M1’ has them all.

This works:

M = 1000*rand(37, 745, 32);             % Create Data
M1 = M((M >= 815.6) & (M <= 816.4));    % Vector Of Desired Values

Matrix dimensions must agree.

i have a 10x10 matrix. I just want to extract the values between 30 and 60 and put them in a vector

never mind. I got it lol
