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

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.

If signal is a number, that number of values are returned.

Example : Create a TARGET where each frame is on a random location on the surface of a sphere of radius 1 Evaluate_Expression /EXPRESSION=RAND(-PI(),PI(),FRAME_NUMBERS::ORIGINAL::FRAMES) /RESULT_TYPES=DERIVED /RESULT_FOLDERS=RADIUS /RESULT_NAME=VERTICAL ! /APPLY_AS_SUFFIX_TO_SIGNAL_NAME=FALSE ; Evaluate_Expression /EXPRESSION=RAND(0,2*PI(),FRAME_NUMBERS::ORIGINAL::FRAMES) /RESULT_TYPES=DERIVED /RESULT_FOLDERS=RADIUS /RESULT_NAME=HORIZONTAL ! /APPLY_AS_SUFFIX_TO_SIGNAL_NAME=FALSE ; Create_Target /SIGNAL_NAMES=SPHERE ! /SIGNAL_DESCRIPTION= /EXPRESSION=VECTOR( COS(DERIVED::RADIUS::VERTICAL)*COS(DERIVED::RADIUS::HORIZONTAL), -COS(DERIVED::RADIUS::VERTICAL)*SIN(DERIVED::RADIUS::HORIZONTAL), SIN(DERIVED::RADIUS::VERTICAL)) ! /INCLUDE_CALFILE=FALSE ;
