i have matrix 51 rows and71 columns and i would like to compute and plot the result of std also i need to compute the confidence intervals 95%?
also after computing the std can i use imagesc command in order to see the range of std for the matrix ?

If you have the Image Processing Toolbox, you can use the std2 function to compute the standard deviation of all the elements of a matrix. If not, you can use std from base MATLAB, but you need to make a vector out of the matrix first.
A = magic(5);
Sorry, but I didn't really understand your second question.
