Illustration of symbolic variable:
When, on the other hand, z is a symbolic variable to start with, quotes are not required around the expression, and the words are automatically collected:
>> z = sym('z');
>> sym(z^3 + 2*z^3)
ans =
3*z^3
When you want to use the multiple variables as symbolic variable names, the syms function is a shortcut rather than of using sym repetitively. The illustration is as follows,
>> syms x y z
does similar thing as
>> x = sym('x');
>> y = sym('y');
Reading from a Mat-File: The load function is used to read from various types of files. As with save function, by default the file will be supposed to be a MAT-file, and load
Illustration of Set operations: For illustration, given the vectors as shown below: >> v1 = 2:6 v1 = 2 3 4 5 6 >> v2 = 1:2:7 v2 = 1 3 5 7
