WebFunctions Programs that accept inputs and return outputs Both scripts and functions allow you to reuse sequences of commands by storing them in program files. Functions provide more flexibility, primarily because you can pass input values and return output values. Webx = 42; if exist ( 'myfunction.m', 'file') && (myfunction (x) >= pi) disp ( 'Expressions are true' ) end The first part of the expression evaluates to false. Therefore, MATLAB does not need to evaluate the second part of the expression, which would result in an undefined function error. Tips You can nest any number of if statements.
