how to extracts each index for each maximum value?

[value index]=max() give only one maximum value and a index. But i need a code that gives each maximum value and their index in both time and frequency domain. how do it?

Answer 1

[Walter Roberson]

value = max(YourVector);
allindex = find(YourVector == value);

A maximum in the time domain is present in all frequencies.

I wonder if you are looking for peaks rather than maximums ?
