Conditional statements enable you to select at run time which block of code to execute. The 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 ...Description. M = max (A) returns the maximum elements of an array. If A is a matrix, then max (A) is a row vector containing the maximum value of each column of A. If A is a multidimensional array, then max (A) operates along the first dimension of A whose size is greater than 1, treating the elements as vectors. Equality of Two Vectors. Create two vectors containing both real and imaginary numbers, then compare the vectors for equality. A = [1+i 3 2 4+i]; B = [1 3+i 2 4+i]; A == B. ans = 1x4 logical array 0 0 1 1. The eq function tests both real and imaginary parts for equality, and returns logical 1 ( true) only where both parts are equal.example. [K,S,P] = lqr (sys,Q,R,N) calculates the optimal gain matrix K, the solution S of the associated algebraic Riccati equation, and the closed-loop poles P for the continuous-time or discrete-time state-space model sys. Q and R are the weight matrices for states and inputs, respectively. The cross term matrix N is set to zero when omitted.Description. TF = isnan (A) returns a logical array containing 1 ( true) where the elements of A are NaN, and 0 ( false) where they are not. If A contains complex numbers, isnan (A) contains 1 for elements with either real or imaginary part is NaN, and 0 for elements where both real and imaginary parts are not NaN.Find the local maxima. The peaks are output in order of occurrence. The first sample is not included despite being the maximum. For the flat peak, the function returns only the point with lowest index. pks = findpeaks (data) pks = 1×3 15 10 20. Use findpeaks without output arguments to display the peaks. Description. TF = contains (str,pat) returns 1 ( true) if str contains the specified pattern, and returns 0 ( false) otherwise. If pat is an array containing multiple patterns, then contains returns 1 if it finds any element of pat in str. If str is a string array or cell array, then TF is a logical array that is the same size as str. 26 Jul 2023 ...
