ggml_diag: Diagonal Matrix (Graph)

In ggmlR: 'GGML' Tensor Operations for Machine Learning

Diagonal Matrix (Graph)

Description

Creates a diagonal matrix from a vector. For vector a[n], produces matrix with a on the diagonal.

Usage

ggml_diag(ctx, a)

Arguments

ctx	GGML context
a	Input vector tensor

Value

Diagonal matrix tensor

Examples

ctx <- ggml_init(16 * 1024 * 1024)
a <- ggml_new_tensor_1d(ctx, GGML_TYPE_F32, 3)
ggml_set_f32(a, c(1, 2, 3))
d <- ggml_diag(ctx, a)  # 3x3 diagonal matrix
graph <- ggml_build_forward_expand(ctx, d)
ggml_graph_compute(ctx, graph)
ggml_free(ctx)
