我想知道是否有一个包在Go中提供有效的元素矩阵运算?类似于GSL的东西?

很容易打电话,例如cblas via cgo:
package main
// #include <cblas.h>
// #cgo LDFLAGS: -L/usr/lib64/atlas -lcblas
import "C"
import "fmt"
type matrix struct {
rows int
cols int
elems []float32
}
func (a matrix) cblasmul(b matrix) (c matrix) {
c = matrix{a.rows, b.cols, make([]float32, a.rows*b.cols)}
C.cblas_sgemm(
C.CblasRowMajor, C.CblasNoTrans, C.CblasNoTrans,
C.int(a.rows), C.int(b.cols), C.int(a.cols),
1.0,
(*C.float)(&a.elems[0]), C.int(a.cols),
(*C.float)(&b.elems[0]), C.int(b.cols),
0.0,
(*C.float)(&c.elems[0]), C.int(c.cols))
return c
}
func main() {
a := matrix{100, 100, make([]float32, 100*100)}
b := matrix{100, 100, make([]float32, 100*100)}
// ...
c := a.cblasmul(b)
fmt.Println(c)
}

对GSL有各种cgo绑定,甚至还有一些纯Go端口的尝试。似乎没有人认可(就星星而言)并且几个月没有活动,但你可能想看一下代码:
