I want after I get the "value", matlab will check "value">=1e-6. If you see the "cross", you're on the right track. Yes, the problem was with "reduced" table -- I imported the excel file as a table. The condition should not work when the distance gets lower than 100 m but only when it reaches 29 m or below, until 100 m. Indeed there is a general approach. rng (s) r1 = randperm (8) r1 = 18 6 3 7 8 5 1 2 4. https://www.mathworks.com/matlabcentral/answers/261613-if-statement-with-multiple-logical-or, https://www.mathworks.com/matlabcentral/answers/261613-if-statement-with-multiple-logical-or#comment_331630, https://www.mathworks.com/matlabcentral/answers/261613-if-statement-with-multiple-logical-or#comment_331634, https://www.mathworks.com/matlabcentral/answers/261613-if-statement-with-multiple-logical-or#answer_204283, https://www.mathworks.com/matlabcentral/answers/261613-if-statement-with-multiple-logical-or#comment_331658. You can use the any function to test if x is equal to any of the elements of the array: if any (x == [5, 6]) % execute code end. Accelerating the pace of engineering and science. In the code, I changed the (e.g.) The first part, 30<=r0, returns 0 (false) or 1 (true). As I've read , matlab will only take the first statement from the left []. This works for numerical arrays. if <expression 1> % Executes when the boolean expression 1 is true if <expression 2> % Executes when the boolean expression 2 is true end end. Just something to be aware of. true || anything is true. Syntax: If (condition) How to test multiple variables for equality against a single value? Other MathWorks country Would salt mines, lakes or flats be reasonably found in high, snowy elevations? Computes the running sum (for element j, the running sum is the sum of the elements from 1 to j, inclusive. (d ~= 1) is true, so MATLAB doesn't need to evaluate the rest of the expression. The code would be in error if any of the Boarder_* variables are not scalars. Basically, after the WHILE statement, I put multiple conditions in order but matlab doesn't work. The syntax for a nested if statement is as follows . Usually RGB colors have values from 0 to 255. The code should cycle through the 10 other voids in the table and if their location is within +/- 50 pixels to the new void then some further code is run. Or ? Learn more about if statement, table, xlsx, elseif For any , this defines a unique sequence with as . sqrtx/b(x) if-1<x<10. Logical Short-Circuiting is a bit different. MathWorks is the leading developer of mathematical computing software for engineers and scientists. Its a sad fact of life that people put operations with side-effects in if statements: Conditional Statements in MATLAB Like other programming languages, MATLAB also provides many conditional statements like the if, if-else, if.else.if, nested if.else, and switch statement. If statement with multiple conditions. It just skipped the if condition. Assign 2on the main diagonal, -1on the adjacent diagonals, and 0everywhere else. Each conditional statement requires the end keyword. but the problem that I still have is regard to text values, that I cannot recall from the table. Sorted by: 6. write a matlab program which takes a number x from user and display the value of the following function f(x) f(x)= x/a(x) if x<=-1. They evaluate an expression or condition and execute the code or statements if the condition is true. sqrtx/b(x) if-1<x<10. *r0(r0_Idx); Thank you very much Alan Stevens, it helped a lot, You may receive emails, depending on your. Definition. Copy and paste the. MathWorks is the leading developer of mathematical computing software for engineers and scientists. This is my code: I stuck at the WHILE LOOP. Robert on 16 Apr 2013. . MATLAB has a command that lets you develop an analytical expression of one or more inputs and assign that expression to a variable.

Perhaps you have stored multiple versions of the M-file and Matlab does not run the file you are expecting. Find the treasures in MATLAB Central and discover how the community can help you! Many thanks!
