Eliminating channels based on coefficient of variance .

1 visualización (últimos 30 días)
1 to 20 columns are the number of channels.
Coeff of Varience is 7.5 which is saved in variable say thresh_cv which I dynamically getting from some header file.
Now if the mean of channel 1(column 1) is less than 7.5 then remove the channnel else keep that channel.
If mean is greater then 7.5 then remove that channel.
can somebody help me the code for all 20 channels(columns)???

So you want to remove every channel whose mean is not presicely 7.5? (which, given floating point maths, would be all of them). I don't really know what coefficient of variance means, though I would have expected to to relate to a measure of variance rather than mean? Given the numbers you show a mean of 7.5 seems very arbitrary!

In case if you want to get the columns which have a mean of 7.5, you can try using "find"
K = find(mean(MATRIX) == 7.5);
requiredMatrix = MATRIX(:,K);
Hope this is what you wanted to know!
