Move down the call stack in debug mode.

📝Syntax

dbdown n

📥Input Arguments

Parameter	Description
n	positive integer scalar specifying the number of levels to move down on the call stack.

📄Description

dbdown changes the current workspace and function context to that of the called function or script while in debug mode. This command is the opposite ofdbup and can only be used after at least one call to dbup.

Each call to dbdown moves one level down the call stack, stopping at the workspace and function context where execution is paused. Execution can continue without returning to the paused line.

dbdown n is equivalent to executing dbdown n times.

This function can only be called from the command line while debugging.

💡Examples

Move between calling and called function workspaces while debugging.

function n = myfile(x)
  n = myfunc(x - 1);
end

function z = myfunc(y)
  z = 2 / y;
end

myfile(1)
