Formatted File Input

Recall, we can open a file for reading by using:

fileID = fopen(filename,'r');

Then, we can use fscanf to read in a formatted file:
A = fscanf(fileID, formatSpec)

Reads and converts data from text file into array A using formatSpec
formatSpec similar to fprintf, additionally:
	Use * to skip field read in
	Can match specific text (e.g., '\nN=' )
	If it cannot match formatSpec to the data, it reads only the portion that matches and stops processing

Can also call with a third argument:
A = fscanf(fileID, formatSpec, sizeA)

sizeA indicates # elements to read into A, 
	Can be scalar int or [m, n] or Inf (reads to end of file)
	1 reads 1 scalar number or 1 string

Note: if data is in rows × cols in the file, read it in [cols, rows] and transpose results
	This happens due to MATLAB reading in column major order (columns first)
