MATLAB: Creating an associated value for an array based upon its position in another matrix

arraysMATLAB

What I am trying to do is associate the y1 value with an SSP(:,2) value depending upon its relationship to SSP(:,1) 's depth.
y1i = 0:-1:-200 ; %a list of depths
SSP(:,1) = 0:-5:-200 ; %is a list of depths, referred to 'depths' below.
depths = SSP(:,1) ;
SSP(:,2) = linspace(1500,1480,41) ; %is a list of speeds, reffered to 'c' below.
c = SSP(:,2) ;
j = numel(depths) ;
k = numel(y1i) ;
for m = 1:k ;
for n = 1:(j-1) ;
y1i(m) <= depths(n) & y1i(m) > depths(n+1) ;
c1(m) = c(n) ;
end
end
I will be grateful for any advice that is given.
Thank you

Hi,
I think the command below should be a conditional statement something like if . 
y1i(m) <= depths(n) & y1i(m) > depths(n+1) ;
Also, I see c1 in the code is not initialized. Since it is changing size every iteration if it is not declared. Although this is not the error you might be facing but it is good practice to initialize the array beforehand.
