ggml_sub: Element-wise Subtraction (Graph)

In ggmlR: 'GGML' Tensor Operations for Machine Learning

Element-wise Subtraction (Graph)

Description

Creates a graph node for element-wise subtraction.

Usage

ggml_sub(ctx, a, b)

Arguments

ctx	GGML context
a	First tensor
b	Second tensor (same shape as a)

Value

Tensor representing the subtraction operation (a - b)

Examples

ctx <- ggml_init(1024 * 1024)
a <- ggml_new_tensor_1d(ctx, GGML_TYPE_F32, 5)
b <- ggml_new_tensor_1d(ctx, GGML_TYPE_F32, 5)
ggml_set_f32(a, c(5, 4, 3, 2, 1))
ggml_set_f32(b, c(1, 1, 1, 1, 1))
result <- ggml_sub(ctx, a, b)
graph <- ggml_build_forward_expand(ctx, result)
ggml_graph_compute(ctx, graph)
ggml_get_f32(result)
ggml_free(ctx)
