arm_pid_f32.c file is not present in CMSIS-DSP library in the keil software

Hello Friends,

i want to use PID Controller for the motor control using LPC1343. The CMSIS-DSP library contains PID motor control. There are 9 functions in the CMSIS-DSP library.

http://www.keil.com/pack/doc/CMSIS/DSP/html/group___p_i_d.html

(link describing the 9 functions)

But in the keil software i found that there are only 6 functions .
i didn't find the last three functions (each function is given as separate .c file)
arm_pid_f32
arm_pid_q31
arm_pid_q15

How can i download those files ???

Thanks for Help in advance.....
