This MATLAB function reads data from an open text file into column vector A and interprets values in the file according to the format specified by formatSpec.
You are right, fscanf can give you the next integer. However, you need to provide it with a pointer. Therefore, you need an & behind number: fscanf(myFile, "%d", &number); *scanf family of functions also automatically skip whitespace (except when given %c, %[or %n). Your loop with reading file will eventually look like this:
Because the MATLAB function readtable is not supported for code generation, the my_readtable function uses low-level file I/O functions like fopen, fgetl, fscanf, feof, and fclose to open, read, and close the file.
fscanf. Read formatted data from file. Syntax. A = fscanf(fid,format) [A,count] = fscanf(fid,format,size) Description.
