what is the correct way to write this expression in matlab?

f=sqrt((1/(L*C)-(R.^2)/((4*C).^2))); correct way to write the expression in matlab?

[Dyuman Joshi]

We don't know, because we don't know the reference for the expression.

Please give more information or provide reference formula.

If ‘R’, ‘L’, and ‘C’ are all arrays of the same size, use element-wise operations in every multiplication, division, and exponentiation operation —

f = sqrt((1./(L.*C)-(R.^2)./((4*C).^2)));

See Array vs. Matrix Operations for details.

We can only see, if the expression is written corretly to allow evaluation by MATLAB:

L=1;
C=2;
R=3;
f=sqrt((1/(L*C)-(R.^2)/((4*C).^2)))

f = 0.5995
