Loading your work

Let us see how one can load the variable(s) stored in a file. First, we clear the workspace to be sure that we actually load the variable prime_sequence stored in the file primes.mat:

octave:46> clear; whos
octave:47> load primes.mat
octave:48> whos
Variables in the current scope:
Attr Name size Bytes Class
==== ==== ==== ===== =====
prime_sequence 1x1385 11080 double

Notice that Octave treats the numbers as doubles, since we have not explicitly told it otherwise.

The general syntax for load is:

load option1 option2 filename

where the options are the same as above for the save command. For example, to load the data stored in the ascii file primes.dat, we can use:

octave:49> load ascii primes.dat
octave:50> whos
Variables in the current scope:
Attr Name size Bytes Class
==== ==== ==== ===== =====
prime_sequence 1x1385 11080 double
primes 1x1385 11080 double

Notice that when loading an ascii file like we did in Command 49, Octave will create a variable called...
