struct UnicodePlot::MatrixView(T)

• UnicodePlot::MatrixView(T)
• Struct
• Value
• Object

Overview

A small internal view over Array(Array(T)).

MatrixView intentionally supports only Array(Array(T)) for now. It centralizes validation for matrix-shaped plot inputs:

• rectangular shape
• row / column dimensions
• indexed access
• cell iteration

It is used by heatmap, spy, contourplot, surfaceplot, and imageplot. MatrixView is not a general AbstractMatrix abstraction.

Defined in:

unicode_plot/matrix.cr

Constructors

• .new(rows : Array(Array(T)))
