This is the first problem in the fast 1-D convolution series. This problem asks you to find a fast algorithm to compute the 1-D convolution in its full output shape.
There exists a fast 1-D convolution algorithm way more efficient than MATLAB's built-in conv function invoked in the form conv(u,v,'full'), and the performance improvement is more pronounced when length(u) and/or length(v) are large. Do you know how? Try it out.
- Next problem: Fast 1-D Convolution (same shape).

The same codes, the score is from 5 to 49, too wide.
score.p is invalid now, the score is size, not speed.
The function conv is not slow. It is like complaining that the function sum is slow. And the only way the function sum can be slow is if we are not using it properly.
