How do you state two conditions for an "if" statement in MATLAB?

Question

I'm completely new to MATLAB and I am writing a function to find diagonal dominance in square matrices of unknown dimensions.

I am calling the matrix "A", then using B=abs(A) to get all the components as positive and C=length(A) to identify the dimensions (I already have programmed the error messages if A isn't square).

My idea is to say "i=1" and then use;

if 2*B(i,i)=>B(i,:)
ddom=1;
else ddom=0;

My idea is then to say that if both i=<C and if ddom=1, i=i+1.

I'm pretty sure my reasoning is fairly sound, but I don't know how to use an "if" statement that is dependant on two conditions.

If anyone could help it'd be really appreciated.

Hey dude,

Here is what you can do,

if ((i<=C)&&(ddom=1))
    i=i+1;
end

The above implies that if the two conditions occur in conjunction, the increment takes place. But if any of them or none is true, MATLAB will skip the increment and continues executing what comes after the if-statement.

Good luck
