Help Center Help Center. An expression is true when its result is nonempty and contains only nonzero elements logical or real numeric. Otherwise, the expression is false. The elseif and else blocks are optional. The statements execute only if previous expressions in the if An if block can include multiple elseif blocks. Loop through the matrix and assign each element a new value. Assign 2 on the main diagonal, -1 on the adjacent diagonals, and 0 everywhere else. If size A and size B are the same, concatenate the arrays; otherwise, display a warning and return an empty array. Use strcmp to compare character vectors. Determine if a value is nonzero.

Loops use a for or while keyword, and conditional statements use if or switch. Additional keywords provide finer control over the program flow. To determine which block of code to execute at run time, use if or switch conditional statements. To repeatedly execute a block of code, use for and while loops.

Often we want to execute a command only if a certain test condition is satisfied. We use if statements to do this. If you want to execute certain commands only when a certain test condition is met, use a simple if statement of the form:. In myfile. In the example above, the test condition on the if statement was satisfied it was true since the value stored in x was indeed great than 4. Because the test condition was true, the statements inside the if were executed, and the final values of x and y after the if statement were different than the initial values. An if, else statement will allow you to execute certain commands if a test condition is true and execute other commands if the test condition is false. The commands inside the else are executed only if the test condition on the if statement is false. If the test condition on the if statement is true, the commands inside the if are executed, and the commands inside the else are skipped. Thus, only the commands inside the if or the commands inside the else will be executed, never both.

For example:. The space creates a nested if statement that requires its own end keyword. Examples collapse all Use if, elseif, and else for Conditional Assignment. Therefore, MATLAB does not need to evaluate the second part of the expression, which would result in an undefined function error.
