1D gaussian filter for A-scans (OCT)

Hello all,

I would like to implement a gaussian filter on my A-scan (1D) from an OCT image (B-scan, 2D). The A-scan essentially represents how the intensity values fluctuate versus the depth.

I would appreciate your help.

Thank you :)

See imgaussfilt, e.g.,

A=zeros(1,11); A((end+1)/2)=1

A = 1x11

0 0 0 0 0 1 0 0 0 0 0

B=imgaussfilt(A,1.2)

B = 1x11

0 0 0.0146 0.0831 0.2356 0.3333 0.2356 0.0831 0.0146 0 0
