Scale a vector

Hello Michael,

Check out the DSPLIB routines for vectors:

DSPLIB: http://www.ti.com/tool/sprc100

short maxidx (DATA *x, ushort ng, ushort ng_size) Index for maximum magnitude in a vector

short maxidx34 (DATA *x, ushort nx) Index of the maximum element of a vector ≤ 34

short maxval (DATA *x, ushort nx) Maximum magnitude in a vector

void maxvec (DATA *x, ushort nx, DATA *r_val,DATA *r_idx) Index and value of the maximum element of a vector

short minidx (DATA *x, ushort nx) Index for minimum magnitude in a vector

short minval (DATA *x, ushort nx) Minimum element in a vector

void minvec (DATA *x, ushort nx, DATA *r_val, DATA *r_idx) Index and value of the minimum element of a vector

ushort mul32 (LDATA *x, LDATA *y, LDATA *r, ushort nx) 32-bit vector multiply

ushort add (DATA *x, DATA *y, DATA *r, ushort nx, ushort scale) Optimized vector addition

short sub (DATA *x, DATA *y, DATA *r, ushort nx, ushort scale) Vector subtraction

Is this what you are looking for?

Hope this helps,
Mark
