Hi,
I have a long matrix of breakpoints: for example, 0.19 0.49 0.69 0.93 1.69
is there an easy function to determine if I have a value of 0.55 for example that this value would fall under the third category since it is between 0.49 and 0.69?

Assuming your breakpoints are sorted (I'll call them breakpoints), you could do something like this:
x = 0.55;
find(breakpoints<x,1,'last')

[v, idx] = histc(x, [-inf breakpoints]);
then the value you want is idx
