hsec

Purpose

Returns the number of hundredths of a second since midnight.

Format

y = hsec
Returns:y (scalar) – hundredths of a second since midnight.

Examples

// Define random x matrix
x = rndu(1000, 1000);

// Starting time
tStart = hsec;

//  Multiply x*x
y = x*x;

// Calculate time elapsed
tTotal = hsec-tStart;

In this example, hsec() is used to time a 1000x1000 multiplication in GAUSS. A 1000x1000 matrix, x, is created, and the current time, in hundredths of a second since midnight, is stored in the variable tStart. Then the multiplication is carried out. Finally, tStart is subtracted from hsec() to give the time difference which is assigned to tTotal.

Remarks

The number of hundredths of a second since midnight can also be accessed as the \([4,1]\) element of the vector returned by the date() function.
