Run Functions in the Editor
This example shows how to run a function that requires some initial setup, such as input
argument values, while working in the Editor.(^1) Create a function in a program file named myfunction.m.
function y = myfunction(x)
y = x.^2 + x;
This function requires input x.
(^2) View the commands available for running the function by clicking Run on the Editor
tab. The command at the top of the list is the command that the Editor uses by
default when you click the Run icon.
(^3) Replace the text type code to run with an expression that allows you to run the
function.
y = myfunction(1:10)
You can enter multiple commands on the same line, such as
x = 1:10; y = myfunction(x)
For more complicated, multiline commands, create a separate script file, and then
run the script.
NoteRun commands use the base workspace. Any variables that you define in a run
command can overwrite variables in the base workspace that have the same name.
(^4) Run the function by clicking Run or a specific run command from the drop-down list.
For myfunction.m, and an input of 1:10, this result appears in the Command
Window:
