Module farr
Functions operating on arrays of floating-point values.
farr_sample_int and farr_sample_float can be used to convert
arrays of ints and floats to arrays of doubles.
| farr_range (x1, x2, dx) |
an array generated between x1 and x2, with delta dx. |
| farr_map (a, f) |
create a new array by applying a function to each value of an array. |
| farr_scale (A, m, c) |
transform an array by multipying its values by m and adding c. |
| farr_from_seq () |
array of doubles from a sequence |
| farr_copy () |
create dynanic array from a statically declared array of doubles. |
| farr_2 (x1, x2) |
double array of two elements. |
| farr_4 (x1, x2, x3, x4) |
double array of four elements. |
