evalTimer

Syntax

evalTimer(funcs, [count=1])

Details

Return the execution time of the specified functions in units of milliseconds. If funcs is a tuple of functions, return the amount of time to execute these functions consecutively.

The difference between statement timer and function evalTimer:

the input of timer is a statement block while the input of evalTimer can only be functions. To use evalTimer to get execution time of a statement block, we need to rewrite the statement block as a user-defined function.
timer returns a message which cannot be assigned to a variable; evalTimer returns a scalar that can be assigned to a variable.

Parameters

funcs is a function or a tuple of functions with no parameters.

count (optional) is a positive number indicating the number of times funcs will be executed. The default value is 1.

Returns

A scalar of type DOUBLE.

Examples

x=rand(10.0, 1000000)
evalTimer(dot{x,2},10);
// output: 39.609375

evalTimer(sort{x},10);
// output: 837.542702

evalTimer([dot{x,2},sort{x}],10)
// output: 870.065348
