SVD reconstruction of waveforms

I have carried out SVD on 13 different waveforms and formed a matrix of 13 column vectors. Now my job is to multiply the first few modes or columns to reconstruct the waveforms. Can anyone help me with it please.

Is this what you want to do?
a = [0:0.1:6*pi]';
z1 = [sin(a) sin(3*a) sin(5*a) sin(7*a)];
z2 = z1(:,1);
for k1 = 1:size(z1,2)-1
z2 = z2.*z1(:,k1+1);
end
figure(1)
plot(a, z1, ':')
hold on
plot(a, z2, '-r')
hold off
grid
