fscanf — Converts formatted input read on a file
[v_1,...v_n]=fscanf (file,format)
Specifies the format conversion.
Specifies the input file name or file number.
The fscanf functions read character data on the file specified by the
file argument , interpret it according

The format parameter contains conversion specifications used to interpret the input.
The format parameter can contain white-space characters (blanks, tabs, newline, or formfeed) that, except in the following two cases, read the input up to the next nonwhite-space character. Unless there is a match in the control string, trailing white space (including a newline character) is not read.
Any character except % (percent sign), which must match the next character of the input stream.
A conversion specification that directs the conversion of the next input field. see scanf_conversion for details.
