sir how to convert 0 to -1 and 1 to +1

Best Answer

% Example input
A = randi([0 1],10,1);

Cellarray lookup table:

B = {'-1', '+1'};
C = B(A+1).';

Or char array table:

B = ['-1'; '+1'];
C = B(A+1,:)

MATLAB: How to determine the mean value every 10 data points and then calculate the standard deviation of the mean values (150)

Suppose A is a column vector 1500x1

A = randn(1500,1);
% first reshape into columns with 10 rows
A = reshape(A,10,150);
% take the means over the columns 
meanz = mean(A);
% now get the standard deviation of the means
std(meanz)

If A is a row vector, you can first transpose and then perform the above.

A = A';
