Julia code for the book Numerical Linear Algebra

To use this code, please download and install Julia from julialang.org/downloads.

Julia installation

Step 1: if you have installed Julia on your computer, you can download this repository using the green Clone or download button above. Once you have Julia installed, you can run all the Julia codes in this repository (files with extension .jl).

To run the Julia notebooks (files with extension .ipynb), you need to install IJulia and Jupyter.

Step 2: IJulia is a Julia package. To install it, start the Julia application. At the julia> prompt, type:

using Pkg
Pkg.add("IJulia")

See IJulia for more detailed instructions.

Step 3: Install Jupyter following these instructions.

Step 4: type jupyter notebook in a terminal window. Make sure you are in the directory containing your notebook. You should be able to open the notebook from the jupyter window inside your web browser.

You can run the example notebook Demo.ipynb contained in this repository. After opening Demo.ipynb, wait for the kernel to be ready (check the top right corner of the window), then click on Cell -> Run All to update the plot. You may have to change the Julia kernel to match the one that is installed. Click on Kernel -> change kernel for this.

Read the notebook. You should see a plot at the end.

You are now ready to go!
