How to do zero padding in matlab?
Zero-padding means that you append an array of zeros to the end of your input signal before you fft it. Luckily, the fft command within Matlab makes it very easy to zero-pad.
How to do zero padding?
In zero padding, you add zeros to the end of the input sequence so that the total number of samples is equal to the next higher power of two. For example, if you have 10 samples of a signal, you can add six zeros to make the total number of samples equal to 16, or 32, which is a power of two.
What does padding do in Matlab?
The output frame has the same dimensions as the input frame. The padding operation assigns a pattern of pixel values to the inactive pixels around a frame. Vision HDL Toolbox algorithms provide padding by constant value, replication, or symmetry.
