MATLAB: How to take moving average with different window shapes

Question

I need to take the sliding window average of a signal/single column matrix using different shapes of moving window (rectangle, blackman harris, etc). So far I can only find ways to take the moving average with a rectangular window (simply taking the moving average of the numbers with a given window size). How can I take the averages through different window shapes?

Thanks

You can use the conv function to calculate the convolution of your window with your data. Just make sure your window has a sum of 1.

You might need to pay special attention to the edges of your data, to make sure conventions conv is using match your expectations.
