load command in matlab loading blank file

Question

I am loading a file in matlab, but it is being loaded as an empty variable.

positive    0x0    []

and am using

 load positive.txt

but the file is not empty. Is the something am wrong? P.S. I have loaded other files from the same folder successfully. Also I tried to rename it to positive.dat but that also didn't work. And it was an excel file that I saved as an text file.

and the first couple entries of the file, copied & pasted

load command is only for MAT-files (file extension .mat) or ASCII files saved in MATLAB format, usually in MATLAB using save command. For all other file formats you should use some other command.

For text files you can use fopen, fscanf, fclose. For binary files you can use fopen, fread, fclose. fopen opens the file for reading and/or writing, fscanf or fread read data from file (fscanf reads text, fread binary data) and then fclose closes the file.

For Excel files you can use xlsread. xlsread does not need fopen or fclose.
