I have 3 signals, size(x)=15001 size(y)=7500 size(z)=3751

and how to bring the sizes of all these three signals to 15000?

 x(end)=[];
y(end+1:15000)=0;
z(end+1:15000)=0;

Thank you so much sir,It worked!!!!

Answer 2

[Walter Roberson]

newx = interp1(linspace(0,1,length(x)), x, linspace(0,1,15000));
newy = interp1(linspace(0,1,length(y)), y, linspace(0,1,15000));
newz = interp1(linspace(0,1,length(z)), z, linspace(0,1,15000));
