Mapping 2 matrices with different number of columns.

Hi,
I've got the following 2 matrices and 1 vector
- UniqFXRates 30x11 double (11 FX rates for 30 data points)
- InstrFXRates 30x232 double (232 companies for the same 30 data points). The unique FX Rates for the 232 companies are 11
- IndFX 1x232 double ("indicator" vector which shows the column's index number of UniqFXRates for each instrument) E.g.: [1 5 11 2 4 2 1 3 ...]
The goal is to map the content from UniqFXRates into InstrFXRates using IndFX vector as an indicator.
The following code unfortunatelly does not work.
InstrFXRates(:,IndFX)=UniqFXRates;
A loop does not work as well.
for instr=IndFX
InstrFXRates=UniqFXRates(:,IndFX);
end
Do you have any suggestions?
Thank you in advance

What does that actually mean? Can you give an example of input and desired output?
