S = readlines (filename,Name,Value) creates a string array from a file with additional options specified by one or more name-value pair arguments. For example, 'EmptyLineRule','skip' skips empty lines.A basic for loop in MATLAB is often used to assign to or access array elements iteratively. For example, let’s say you have a vector A, and you want to simply display each value one at a time: Theme. Copy. A = [3 6 9 4 1]; for i = 1:length (A) disp (A (i)) end. For more examples using for loops, see:Apr 11, 2014 · The code you show would be in a loop. Change the "exit" to "break" to cause the code to exit the loop and continue on with the next statement after the loop. C = A + B adds arrays A and B by adding corresponding elements. If one input is a string array, then plus appends the corresponding elements as strings. The sizes of A and B must be the same or be compatible. If the sizes of A and B are compatible, then the two arrays implicitly expand to match each other. For example, if one of A or B is a ...

Approximate Derivatives with diff. Use the diff function to approximate partial derivatives with the syntax Y = diff (f)/h, where f is a vector of function values evaluated over some domain, X, and h is an appropriate step size. For example, the first derivative of sin (x) with respect to x is cos (x), and the second derivative with respect to ...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*. Description. k = find (X) returns a vector containing the linear indices of each nonzero element in array X. If X is a vector, then find returns a vector with the same orientation as X. If X is a multidimensional array, then find returns a column vector of the linear indices of the result. k = find (X,n) returns the first n indices ...Because two NaN s are not equal to each other, logical operations involving NaN always return false, except for a test for inequality, ( NaN ~= NaN ): NaN > NaN ans = 0 NaN ~= NaN ans = 1. MATLAB represents infinity by the special value inf, and values that are neither real nor complex by the special value NaN, which stands for “Not a Number”.If you do not end the function with an end statement, MATLAB behaves as if the end of the function occurs immediately before the start of the next function. In the Live Editor, you cannot add section breaks inside a function. Sections inside local functions are not supported. If you add local functions to a live script, MATLAB adds a section ...end. %example: A=rand (1,2,5,3); This also works in other calls: Copy. %example: A=rand (1,2,5,3); So in your code end+1 means that you are assigning a value to the next position, which automatically extends the array to fit that size. NB: I disagree with using i and j as variables here, as well as the lack of any comments whatsoever.A = fscanf (fileID,formatSpec) reads data from an open text file into column vector A and interprets values in the file according to the format specified by formatSpec . The fscanf function reapplies the format throughout the entire file and positions the file pointer at the end-of-file marker. If fscanf cannot match formatSpec to the data, it ...return forces MATLAB ® to return control to the invoking program before it reaches the end of the script or function. The invoking program is a script or function that calls the script or function containing the call to return.If you call the script or function that contains return directly, there is no invoking program and MATLAB returns control to the command prompt.The end operator is just a shorthand for length (var). You can even do stuff like var (1:end/2) to get the first half of your variable. For more than 1 dimension, the end operator acts as size (var, x), where x is the current dimension. Attention: Matlab does not use zero based indexing, i.e. accessing array (length (array)) is actually correct ...Run the code in the selected section.
