Can I use a look-up vector table to interpolate values?

In matlab, let's say I have a=[0 4.2 7.4 11.2] and b=[0 2 12 4 5.3 7.4 11 16]. I want to see where each value of b fits in a and return the lowest INDEX of the 2 boundaries. Thus, I'd like to have in the end a vector (same length as b) containing the respective indexes. c=[1 1 4 1 2 3 3 4] because, for example, 4.2<5.3<7.4, so I return the index of 4.2, which is 2. Hope I didn't make any mistakes and I was clear enough. Thanks in advance.

See histc() when used in the two-output form.

[N,BIN] = histc(a,b) does the trick. Thanks
