i have a curve ([0:20:50000],x(:,3)) I want to calculate the magnitude of this curve, but i obtain zero. Th curve is attache
index=1;
for i=0:20:50000
xm=(max(x(:,3))-min(x(:,3)));
xlm(index)=xm;
index=index+1;
end

What is your definition of magnitude for this signal which is not periodic

What do you mean by magnitude? Is it that you want to calculate the length of the curve?
