WebDec 18, 2024 · First of all, see what is the syntax of matrix inverse in MATLAB. Syntax A = inv (B) where B is the square matrix and A is the inverse of matrix B. Let us take a few examples to see how you find matrix inverse easily. Example-1: Find the inverse of the following 2 x 2 matrix MATLAB code B = [2 3; 5 7]; A = inv(B) Output Explanation WebHow can I do the inverse laplace transform of 1/ (s-a)? • ( 1 vote) David 10 years ago That's 1/s shifted by a. And you can shift by a by multiplying your function f (t) with e^-at. Since L {1} = 1/s and therefore f (t) = 1, L { e^-at*f (t) } = 1/ (s-a). Of course if s is equal or greater than a.
