In mSTEM: Multiple Testing of Local Extrema for Detection of Change Points

Description

Compute convolution function using FFT, similar to the function 'conv' in matlab

Usage

conv(u, v, shape = c("same", "full"))

Arguments

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

Value

a vector of convolution, as specified by shape.

References

Examples

u = c(-1,2,3,-2,0,1,2)
v = c(2,4,-1,1)
w = conv(u,v,'same')
