hi, i'm trying to use the find function to locate specific values form matrix array and to remove them (as you can see in the attached m-file) https://www.dropbox.com/s/bcynkiblh7n8tr5/check_values_s_ds_script.m
i use the function like this:
[row,col] = find(resault>0.899 & resault < 1);
but still i find values that are greater then 1 (some are even 50) what am i doing wrong?

I don't know how you got those figures, but I can assure you that
row,col] = find(resault>0.899 & resault < 1)
will find only location of numbers that are between 0.899 and 1

row and col are the indices in the matrix which have the value you need. Find function just finds the indices which satisfy the condition, however find function does not replaces those values.

What you want is
resault(resault>0.899 & resault < 1)
Maybe what you mean by remove them
resault(resault>0.899 & resault < 1)=0
Removing an element doesn't mean set it to zero. Also you can't remove a element from a nxm matrix, you can remove an entire column or row.
