Importdata Command not accepting input argument

2 views (last 30 days)
Hello, Well I know this should be a pretty simple task, but I have been unable to use the importdata command. what I have is this
ans =
>> importdata(FILENAMES{j})
??? Error using ==> importdata at 136
Unable to open file.
The file is there because when I use the command in this way
>> importdata('L1S11_0_0.mat')
ans =
cycles: 0
load: 0
comment: 'Baseline'
condition: 'Baseline'
path_data: [1x252 struct]
straingage_data: [1x1 struct]
XRay_data: [1x1 struct]
It works perfectly.
I have +100 files to import and I cant simply write the names manually each time with every importdata command.
Can you say what could I be doing wrong?
By the way: I am using Matlab R2010a

when I run the line
strcmp(FILENAMES{j}, 'L1S11_0_0.mat')
It returns a "0". They should be the same so why is matlab taking them as different? (The difference is in the presence or lack of the '' sign)

Filenames seems to be a cell of cells, you can tell from ans being 'L1S11_0_0.mat' rather than just L1S11_0_0.mat. This should work:

Any ideas of how could I refer this problem? Matlab is not taking the variables to have the same value (FILENAMES and 'L1SS1_0_0')
