MATLAB: Find the index of the lowest number greater than zero in a vector

numbervector

I would like to find the index of the lowest number greater than zero in a vector. ex: [0,0,4,5,0] The answer should be 3 because 4 is the third element.

Best Answer

A(A==0)=inf
[~,idx]=min(A)

MATLAB: How to find the index location of repeated consecutive numbers over a tolerance within a vector

This should work better. Did not previously think about multi-digit numbers.

n=7;%minimum number of repeats
a=num2str(~(diff(A)==0));
a=a(a~=' ');
idx=strfind(a,repmat('0',1,n-1));
