A 90-degree phase shifted sine wave is just a cosine wave. So if that is literally what you want to do then just create a cosine instead of a sine.

t = linspace(0,2*pi) ;
x = sin(pi/4*t) ;
plot(t,x,'r')
hold on
x = sin(pi/4*t+pi/2) ; % phase shift by pi/2, which is same as cos
plot(t,x,'b')

You can use a hilbert transform and then take just the imaginary part of it.
x_shifted=imag(hilbert(x));
