Based on the file format of the input file, importdata calls a helper function to read the data. When the helper function returns more than one nonempty output, importdata combines the outputs into a struct array.

MATLAB includes functions tailored to import specific file formats. Consider using format-specific functions when you want to import an entire file or only a portion of a file.
A = fscanf(fileID,formatSpec) reads data from an open text file into column vector A and interprets values in the file according to the format specified by formatSpec. The fscanf function reapplies the format throughout the entire file and positions the file pointer at the end-of-file marker.

MATLAB has two general types of text file input functions. If the data is organized as a table (i.e., a series of rows, where each row has the same number of values separated by white space), then use the textread () or the textscan () function.
Reading Data in a Formatted Pattern. To import text files that importdata and textscan cannot read, consider using fscanf. The fscanf function requires that you describe the format of your file, but includes many options for this format description.
example. load (filename,"-mat") treats filename as a MAT-file, regardless of the file extension. load (filename,"-mat",variables) loads the specified variables from filename. S = load (___) loads data into S, using any of the input argument combinations in previous syntaxes.
