ggml_neg: Negation (Graph)

In ggmlR: 'GGML' Tensor Operations for Machine Learning

Negation (Graph)

Description

Creates a graph node for element-wise negation: -x

Usage

ggml_neg(ctx, a)

Arguments

ctx	GGML context
a	Input tensor

Value

Tensor representing the negation operation

Examples

ctx <- ggml_init(16 * 1024 * 1024)
a <- ggml_new_tensor_1d(ctx, GGML_TYPE_F32, 4)
ggml_set_f32(a, c(1, -2, 3, -4))
result <- ggml_neg(ctx, a)
graph <- ggml_build_forward_expand(ctx, result)
ggml_graph_compute(ctx, graph)
output <- ggml_get_f32(result)  # [-1, 2, -3, 4]
ggml_free(ctx)
