Find Array Elements That Meet a Condition - MATLAB

WebDescription. M = min (A) returns the minimum elements of an array. If A is a matrix, then min (A) is a row vector containing the minimum value of each column of A. If A is a multidimensional array, then min (A) operates along the first dimension of A whose size is greater than 1, treating the elements as vectors. WebSome problems require information about the locations of the array elements that meet a condition rather than their actual values. In this example, you can use the find function to locate all of the elements in A less than 9. I = find (A < 9) I = 8×1 3 6 7 11 14 16 17 22.

WebCalculate the integral of a vector where the spacing between data points is 1. Create a numeric vector of data. Y = [1 4 9 16 25]; Y contains function values for f ( x) = x 2 in the domain [1, 5]. Use trapz to integrate the data with unit spacing. Q = trapz (Y) Q = 42. This approximate integration yields a value of 42. WebBecause y (x) is a symbolic function, you can directly evaluate it for values of x. Evaluate y (x) at -2, 0, and 2. Because y (x) is undefined at x = 0, the value is NaN.
