MeshGrid.jl

Overview

MeshGrid.jl is a simple Julia module that provides functionality similar to MATLAB's meshgrid function. It generates coordinate matrices from vectors or ranges, which are useful for evaluating functions over a grid in two or three dimensions.

Installation

To install MeshGrid.jl, use the following command in the Julia REPL:

using Pkg
Pkg.add("MeshGrid")

Some Examples

These examples illustrate how MeshGrid.jl can handle different data types and mixed types. This flexibility makes it easier to translate MATLAB code into Julia, providing a familiar interface for those transitioning from MATLAB to Julia. Note that the element data type of the output grid will be the promotion of the input element data types.

Example 1: Creating 2D Grid from Range

x = -1:1:1
y = -1:0.5:1

X, Y = meshgrid(x, y)

Example 2: Mixing Integers and Floats in 2D Grid

x = 1:3  # integer range
y = [1.0, 2.5, 4.0]  # Float vector

X, Y = meshgrid(x, y) # elements are promoted to Float64

Example 3: Fusing Different Data Types to form 3D Grid

x = 1:3  # integer range
y = [1.0, 2.5, 4.0]  # float vector
z = ["alice", "bob"] # string vector

X, Y, Z = meshgrid(x, y, z) # elements are promoted to Any
