Description. Y = cos (X) returns the cosine for each element of X. The cos function operates element-wise on arrays. The function accepts both real and complex inputs. For real values of X, cos (X) returns real values in the interval [-1, 1]. For complex values of X , cos (X) returns complex values.

See the complete set of rules in Find a Default Symbolic Variable. In the preceding example, diff(f) takes the derivative of f with respect to t because the letter t is closer to x in the alphabet than the letter s is. To determine the default variable that MATLAB differentiates with respect to, use symvar:P = prctile (A,p) returns percentiles of elements in input data A for the percentages p in the interval [0,100]. If A is a vector, then P is a scalar or a vector with the same length as p. P (i) contains the p (i) percentile. If A is a matrix, then P is a row vector or a matrix, where the number of rows of P is equal to length (p).By default, regexp performs case-sensitive matching. str = 'A character vector with UPPERCASE and lowercase text.' ; expression = '\w*case' ; matchStr = regexp (str,expression, 'match') The regular expression specifies that the character vector: Begins with any number of alphanumeric or underscore characters, \w*.Scalar — fzero begins at x0 and tries to locate a point x1 where fun(x1) has the opposite sign of fun(x0).Then fzero iteratively shrinks the interval where fun changes sign to reach a solution.. 2-element vector — fzero checks that fun(x0(1)) and fun(x0(2)) have opposite signs, and errors if they do not. It then iteratively shrinks the interval where fun changes …Count the number of occurrences of the string, red, in string arrays. You can create a string using double quotes. str = "paired with red shoes". str = "paired with red shoes". To count the occurrences of red, use the count function. In this example, the result is 2 because red is also part of the word paired. Store Path to MATLAB® Current Folder. Change the current folder to a local folder and store the path. cd c:\myMATLABFiles currentFolder = pwd. currentFolder = 'c:\myMATLABFiles'.Elements Equal to Specific Values. To find a specific integer value, use the == operator. For instance, find the element equal to 13 in a 1-by-10 vector of odd integers. x = 1:2:20. x = 1×10 1 3 5 7 9 11 13 15 17 19. k = find (x==13) k = 7. To find a noninteger value, use a tolerance value based on your data.Description. L = tril (A) returns the lower triangular portion of matrix A. L = tril (A,k) returns the elements on and below the kth diagonal of A.The variable k does not exist in the MATLAB® workspace and must be accessed using parameters. Restrict the solution to 0 < x < 2 π. Find a valid value of k for this restriction. Assume the condition, conditions, and use solve to find k. Substitute the value of k found into the solution for x. To determine the default variable that MATLAB differentiates with respect to, use symvar: symvar (f,1) ans = t. Calculate the second derivative of f with respect to t: diff (f,t,2) This command returns. ans = -s^2*sin (s*t) Note that diff (f,2) returns the same answer because t is the default variable.

A good way to visualize this concept is with a matrix. While the following array is displayed as a 3-by-3 matrix, MATLAB stores it as a single column made up of the columns of A appended one after the other. P = prctile (A,p) returns percentiles of elements in input data A for the percentages p in the interval [0,100]. If A is a vector, then P is a scalar or a vector with the same length as p. P (i) contains the p (i) percentile. If A is a matrix, then P is a row vector or a matrix, where the number of rows of P is equal to length (p).Scalar — fzero begins at x0 and tries to locate a point x1 where fun(x1) has the opposite sign of fun(x0).Then fzero iteratively shrinks the interval where fun changes sign to reach a solution.. 2-element vector — fzero checks that fun(x0(1)) and fun(x0(2)) have opposite signs, and errors if they do not. It then iteratively shrinks the interval where fun changes …Cell arrays in MATLAB store data of various data types as a cell. These cells could contain data of different types but belong to the same array. Now, this article is focused on finding an exact string in a cell array in MATLAB. This can be done easily by using a combination of two MATLAB functions, the strcmp() and find() functions.example. B = A.' returns the nonconjugate transpose of A, that is, interchanges the row and column index for each element. If A contains complex elements, then A.' does not affect the sign of the imaginary parts. For example, if A (3,2) is 1+2i and B = A.', then the element B (2,3) is also 1+2i. B = transpose (A) is an alternate way to execute ...
