MATLAB: R[1;-1] how i write the program in matlab for random selection between 1 and -1

MATLAB

need help

Best Answer

V = 1 - 2 * randi([0,1])

V = 1 - 2 * (rand >= 0.5)

With N an integer between 1 and 53 (inclusive)

randi([0 2^N-1])/(2^N)

provided that randi is truly uniform random.

MATLAB: Matrix[1,1,1,1;-1,-1,-1,-1;1,1,1,1] to vector[1,1,1,1,-1,-1,-1,-1,1,1,1,1]

I believe you intended semicolons (;) instead of colons (:) in your matrix definition.

To convert it to a vector, use the reshape function:

Matrix = [1,1,1,1; -1,-1,-1,-1; 1,1,1,1];
Vector = reshape(Matrix', 1, [])
Vector =
       1     1     1     1    -1    -1    -1    -1     1     1     1     1

EDIT — Added output of ‘Vector’.
