We can perform the partial fraction expansion by hand, or use a tool like MatLab. If we do it by hand, we get: Cross multiply to find coefficients. Equate terms with like powers of s . From the bottom equation we get A=4, which yields (from the other two equations) B=-4 and C=-2.8. Thus, our equation becomesThe simplest conditional statement is an if statement. For example: % Generate a random number a = randi (100, 1); % If it is even, divide by 2 if rem (a, 2) == 0 disp ('a is even') b = a/2; end. if statements can include alternate choices, using the optional keywords elseif or else . For example:Description. if expression, statements, end evaluates an expression , and executes a group of statements when the expression is true. An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric). Otherwise, the expression is false. The elseif and else blocks are optional.BW = imbinarize (I) creates a binary image from 2-D or 3-D grayscale image I by replacing all values above a globally determined threshold with 1 s and setting all other values to 0 s. By default, imbinarize uses Otsu's method, which chooses the threshold value to minimize the intraclass variance of the thresholded black and white pixels [1 ...
