Given two arrays of double of different sizes (A = 1054x1 and B = 601x1) how is it possible to perform an interpolation ??

It depends on how you want to interpolate them. The‘safest’ way is likely to interpolate the longer vector to the length of the shorter vector:
A = sin((0:1053)/105)';
B = cos((0:600)/30)';
Ai = interp1((1:numel(A))', A, (1:numel(B)), 'linear', 'extrap');
You can then see the result (a sort of Lissajous figure):
figure
plot(Ai, B)
grid
