Matrix of real valued data.
This file specifies the fmat_t type, which is used in aubio to store arrays of floating point values.
Definition in file fmat.h.
| void del_fmat | ( | fmat_t * | s | ) | 
fmat_t buffer deletion function
| s | buffer to delete as returned by new_fmat() | 
read channel vector from a buffer
| s | vector to read from | 
| channel | channel to read from | 
| output | fvec_t to output to | 
get vector buffer from an fmat data
| s | vector to read from | 
| channel | channel to read from | 
read sample value in a buffer
| s | vector to read from | 
| channel | channel to read from | 
| position | sample position to read from | 
| void fmat_ones | ( | fmat_t * | s | ) | 
| void fmat_print | ( | const fmat_t * | s | ) | 
print out fmat data
| s | vector to print out | 
| void fmat_rev | ( | fmat_t * | s | ) | 
set all elements to a given value
| s | vector to modify | 
| val | value to set elements to | 
write sample value in a buffer
| s | vector to write to | 
| data | value to write in s->data[channel][position] | 
| channel | channel to write to | 
| position | sample position to write to | 
compute the product of a matrix by a vector
| s | matrix to compute product with | 
| scale | vector to compute product with | 
| output | vector to store restults in | 
apply weight to vector
If the weight vector is longer than s, only the first elements are used. If the weight vector is shorter than s, the last elements of s are not weighted.
| s | vector to weight | 
| weight | weighting coefficients | 
| void fmat_zeros | ( | fmat_t * | s | ) | 
set all elements to zero
| s | vector to modify | 
fmat_t buffer creation function
| length | the length of the matrix to create | 
| height | the height of the matrix to create |
