I tried to write the code but it did not work at all.. If statement in matlab

In MATLAB®, an empty array has at least one dimension length equal to zero. An array containing missing values, such as NaN or <undefined>, is not necessarily empty. Create a categorical vector with missing values. Since cat1 does not have a dimension of length zero, it is not empty. Create a 0-by-0 categorical array and test if it is empty.Some 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.Link. Theme. Copy. for k = size (x,2): -1 : 1.

Given the following MATLAB code, determine the final value for variable x after the code executes. x=4 x=3*x+1 x=[x 2*x 0] This example has three commands. The first command is x=4 which sets variable x to have a value of the number 4. Whatever variable ...Evaluate Inequalities or Conditions. Define a range for a variable by combining two inequalities into a logical condition using &. syms x range = 0 < x & x < 1; Return the condition at 1/2 and 10 by substituting for x using subs. The subs function does not evaluate the conditions automatically. x1 = subs (range,x,1/2) x2 = subs (range,x,10)Using AND Operator in “if” statements. MATLAB Code Analyzer issues this warning message: "When both arguments are numeric scalars, consider replacing & with …Misinterpreted your "if" statement on my previous attempt. This should be what you are after. Note: "all" will return TRUE if and only if the entire array returned from "x<xmax" is all 1's. "any" will return TRUE if there is one or more 1 in the array returned by "x<xmax".Learn more about matlab, if statement MATLAB Hi, so I'm working on a problem and have an if statement nested in a for-loop.

Copy. if Gas_driven (n) == {'Air'} Also note that == does not check if two strings are the same: you need to use strcmp or strcmpi, exactly as per Ilham Hardy's answer. Sign in to comment.MATLAB determines callback interruption behavior whenever it executes a command that processes the callback queue. These commands include drawnow, figure, uifigure, getframe, waitfor, and pause. If the running callback does not contain one of these commands, then no interruption occurs. MATLAB first finishes executing the running …0. Thomas's answer is an excellent explanation of what's going on here; another way that you can compare a variable to multiple answers is using the any () function. solutions = [3 4]; any (a==solutions); The a==solutions line creates a matrix the same size as solutions, which contains 1's in indecies which where the conditional is true, and 0 ...1.
