broadcast_dims: Expand an array to a larger set of labelled dimensions

In mizer: Dynamic Multi-Species Size Spectrum Modelling

Expand an array to a larger set of labelled dimensions

Description

Internal helper for sizeIntegral(). Replicates x along the dimensions it does not have and permutes its dimensions into the order given by target_labels, so that arrays with different dimensions can be multiplied together elementwise.

Usage

broadcast_dims(x, labels, target_labels, extent)

Arguments

x	An array, vector or scalar.
labels	The dimension labels of x.
target_labels	The dimension labels of the result. Must contain all of labels.
extent	A named vector giving the extent of each label.

Value

An array with dimensions extent[target_labels].
