Reading from a file, MATLAB Programming

Assignment Help:

Reading from a File:

A file has been once created; it can be read into a matrix variable. When the file is a data file, the load function will read from the file filename.ext (example, the extension may be .dat) and generate a matrix with similar name as the file. For illustration, if the data file testfile.dat had been generated, this would read from it:

>> clear

>> load testfile.dat

>> who

Your variables are:

testfile

>> testfile

testfile =

Note: The load command works only if there are similar numbers of values in each line, so that the data can be stored in a matrix and the save command only writes from the matrix to a file. If this is not the situation, the lower-level file I/O functions should be used.
