rand(lo_value,hi_value,signal) - random number in the range (lo_value,hi_value)

<code> Example : rand() will generate a random number in the range 0 to 1

Set_Pipeline_Parameter_From_Expression /PARAMETER_NAME=TEST1 /EXPRESSION=RAND() /AS_INTEGER=FALSE ;

TEST1 = 0.220525

Example : rand(lo_value,hi_value) will generate a random number in the range lo_value to hi_value

Set_Pipeline_Parameter_From_Expression /PARAMETER_NAME=TEST2 /EXPRESSION=RAND(2,3) /AS_INTEGER=FALSE ;

TEST2 = 2.232995

Example : rand(lo_value,hi_value,signal) will generate a random number in the range lo_value to hi_value with the same number of components and frames as signal.

Set_Pipeline_Parameter_From_Expression /PARAMETER_NAME=TEST3 /EXPRESSION=RAND(2,3,FRAME_NUMBERS::ORIGINAL::FRAMES) /AS_INTEGER=FALSE ;

::TEST3 = 2.808424+2.582592+2.346721+2.697052+2.662510+2.861250+2.843808+…(to number of frames)

Example : rand(lo_value,hi_value,signal). If signal is a number, that number of values are returned.

Set_Pipeline_Parameter_From_Expression /PARAMETER_NAME=TEST4 /EXPRESSION=RAND(2,3,3) /AS_INTEGER=FALSE ;

::TEST4 = 2.446495 + 2.718410 + 2.201863

Example : Create a TARGET with random values between 0 and 1

Create_Target /SIGNAL_NAMES=TEST5 ! /SIGNAL_DESCRIPTION= /EXPRESSION=RAND(0,1,TARGET::ORIGINAL::LFT1) ! /INCLUDE_CALFILE=FALSE ;

View the resulting signal in the 3D viewer by turning on the target trail

Example: create a TARGET with random values between 0 and 1.

Create_Target /SIGNAL_NAMES=TEST6 ! /SIGNAL_DESCRIPTION= /EXPRESSION=VECTOR(RAND(0,1,FRAME_NUMBERS::ORIGINAL::FRAMES),RAND(0,1,FRAME_NUMBERS::ORIGINAL::FRAMES),RAND(0,1,FRAME_NUMBERS::ORIGINAL::FRAMES)) ! /INCLUDE_CALFILE=FALSE ;

Note that all components contain different values

Example : Create a TARGET where each frame is on a random location on the surface of a sphere of radius 1
