Hi, I'm new to matlab and my english is not the best. I have a special data format called .sir which has picture data and header info in it. To load the data i already have a given function called loadsir.m:

[image, head, descrip, iaopt]=loadsir(filename)

To load a data into matlab i only have to write e.g. filename = 'queh-a-NAf00-001-004.sir'. Thats working great. But i have about 1000 of this datas in my directory. Somebody could give me a code to read them all in so i dont have to change the filename manually for every data?

Thanks a lot

在 MATLAB Online 中打开

yourfolder='E:\answer\*.sir';
repertoir=dir(yourfolder);
files={repertoir.name}

Ok great, Thanks. Now i have a array with all the filenames in my directory right?

Using loadsir.m gives me this message now:

>> [image, head, descrip, iaopt]=loadsir(files) Error using fopen. First input must be a file name of type char, or a file identifier of type double.

Error in loadsir (line 143) fid=fopen(filename,'r','ieee-be');

Sorry, writing my bachelorthesis and dont have that much time to learn all the matlab basics :).

Ok sry. Used now:

[image, head, descrip, iaopt]=loadsir(files{1,100})

And it works! But he only saves the last array in [image] of course. How can i count up image,image1,image2 so that he saves them all in different arrays?
