When I make a program, I've got a question. In C/C++, before using a variable, should define or at least declare the variable like the following.
int a = 2;
However in MATLAB, Can I just declare a variable? In other words, is

No. Different paradigm. Matlab is weakly typed. Double is the default type. Implicit conversions everywhere.
dummy = '3' * 5
dummy = 'θ' - pi
If you need it to exist before using it (why?), you can declare it to be empty.
a = ;
And go on your merry way.
