MATLAB: Equations, scalars, and matrices

functionsmatricesscalars

I'm supposed to write a program that takes an equation and will accept a scalar, a vector, or matrix.

I know to use ^ when dealing with scalars, and .^ when dealing with vectors/ matrices, but is there a way that will accept both?

I hope this question is clear.

Thanks,

Emmanuel

You can use .^

Please try the following:

   X = [ 5 171 ; 5 300 ; 5 530 ; 5 700 ];
   M = 173;
   N = 712;
   Y = zeros(M,N);
   idx = M*(X(:,2)-1) + X(:,1) ;
   Y(idx) = 1;
   sum(Y(:))

HTH.

Rick
