conv {mSTEM} | R Documentation |
Compute convolution function using FFT, similar to the function 'conv' in matlab
conv(u, v, shape = c("same", "full"))
u |
vector |
v |
vector |
shape |
if 'same', return central part of the convolution,the same size as u; ortherwise return the whole sequence with size lenth(u)+length(v)-1 |
a vector of convolution, as specified by shape.
Matlab document on 'conv' https://www.mathworks.com/help/matlab/ref/conv.html
u = c(-1,2,3,-2,0,1,2)
v = c(2,4,-1,1)
w = conv(u,v,'same')
