How to extract certain files according to numbers in the filename?

Hello,

So i have files with names as shown below:

bar_3pressure.xlsx

bar_3temp.xlsx

bar_4pressure.xlsx

bar_4temp.xlsx

this goes on..where the numbers represent months. I have a loop which requires i read the files for each month to perform certain calculations. Each iteration being a separate month. So first i would do the calculations for march (using only bar_3press..and bar_3temp.xlsx), next iteration april (using only bar_4pressure and bar_4temp)etc. How can i change the input files accordingly? As in how can i specify the file name that is being read.

thanks!

n = 3; % for month #3
filename = sprintf('bar_%dpressure.xlsx', n)

Result

filename =
    'bar_3pressure.xlsx'
