read several csv files with space in the name format

Hi

I am trying to read several csv file

opt.w.matrix.reg. 1 ( please note there is space between . and 1 )

opt.w.matrix.reg. 2

:

:

etc

In order to do that I used first the following :

filename2 = strcat('opt.w.matrix.reg. ',int2str(i),'.csv')

However when I display the file name I received : opt.w.matrix.reg.1

the name does not contain space between the . and the number 1 while the original files have this space.

How can I edit the syntax to have the space in the name.

i = 1;
filename2 = strcat('opt.w.matrix.reg. ',int2str(i),'.csv')

filename2 = 'opt.w.matrix.reg.1.csv'

As you have seen, strcat strips leading and trailing spaces. Use sprintf instead.

filename3 = sprintf('opt.w.matrix.reg. %d.csv', i)

filename3 = 'opt.w.matrix.reg. 1.csv'
