Anonymous Function Matlab Multiple Outputs

After many years of frustration with the fact that matlab does not allow multiple outputs from anonymous functions i have finally come up with a solution. Anonymous functions can accept multiple inputs and return one output. You can inherently get multiple outputs from an anonymous function if the function being called returns more than a single output.

By the way writing these functions that operate on other functions is part of the functional programming style and we re just scratching the surface.

Anonymous function matlab multiple outputs.

But anonymous functions are not allowed more than one outputs. Define a function in a file named stat m that returns the mean and standard deviation of an input vector. I have created a function called mydeal m which i put in my matlab directory. Fdoubleeig x eig 2 x fdoubleeig x eig 2 x let s ask for a single output first.

They can contain only a single executable statement. An anonymous function is a function that is not stored in a program file but is associated with a variable whose data type is function handle. I also noticed if i write calling function without semicolon s p sommaprodotto val1 val2 i get both values in the command window but not in the working space why. Compute the value of the integrand at 2 pi 3.

That takes care of map which we can now use anywhere to send a set of inputs to numerous functions and collect their multiple outputs with brief and easy to read code. Anonymous functions can accept multiple inputs and return one output. Function varargout mydeal x. For example create a handle to an anonymous function that finds the square of.

Learn more about functions. It s not elegant but it works. For example create a handle to an anonymous function that finds the square of. I click on run button but i only get the first value why.

Eonly fdoubleeig magic 3 eonly 30 0000 9 7980 9 7980. I have an anonymous function that gives two output and what it does is takes an index x to a vector rowvalues and then gives two outputs where the first one is all the non zero elements in a 9 element window centered at x and the second output is a vector of length of first output and where all elements are just the element present at the index x. Including functions in scripts requires matlab r2016b or later. An anonymous function is a function that is not stored in a program file but is associated with a variable whose data type is function handle.

This is clearly a simplified example the application is for a nonlinear programming problem where out1 is the objective function and out2 is the gradient calculation. I am not sure how i can structure this differently or in a way which is acceptable by matlab syntax. They can contain only a single executable statement. Function with multiple outputs.
