Matrix.diag

Makes a diagonal matrix from a vector.

struct Matrix(T, ubyte R, ubyte C = R, MatrixOrder O = CurrentMatrixOrder)

static pure nothrow @safe @nogc

static if(O == MatrixOrder.RowMajor)

static if(isSquare && R > 2)

diag

(

Vector!(T, R) v

)

if (

R >= 2 &&

R <= 4

C >= 2

C <= 4

)

Examples

auto v1 = Vector!(int, 3)(4, 5, -1);
auto m1 = Matrix!(int, 3).diag(v1);
assert (m1.v == [4, 0, 0, /**/ 0, 5, 0, /**/ 0, 0, -1]);
