Hey everyone!

Basically im trying to write my fist line of code, in matlab, to the given formula: |G(jw) |= 1/√(R^2+(wL- 1/wC)^2 ) Now, im not sure how to get the 1/wC term as I do not know how to divide in matlab. also, how do I get the ^2? All I want is the general form as an answer. I should be able to get it from there! Thanks!

*  % matrix multiply
.* %scalar multiply
/  % matrix divide
./ % scalar divide
^  % exponentiation
.^ % element-by-element exponentiation

so for your equation:

1./sqrt((R.^2+(w.*L-1/(w.*c)).^2));

1/sqrt(R^2+(w*L-1/(w*C))^2)

if perhaps you are working with arrays or vectors and you want the operations to be performed element wise you must put a period before the symbols like this:
