Tex series: drawing with MATLAB and latex

The purpose is to plot in MATLAB and use pgfplots in latex to modify the graph, such as coordinate system, coordinate axis mark, and title. This ensures the consistency between the markup in the graph and the text in the text, and makes use of MATLAB's powerful data processing and rich plotting functions. The entire process is smooth. You can try it.

 

Assume that the latex file is in the E: \ Tex folder. The script file consisting of the following Matlab code is saved in this folder. Change the current directory of MATLAB to E: \ Tex, run the MATLAB script to obtain the following pdf file in the current directory.

 

Matlab code:

% First figure figname = 'fig1'; % plot x = linspace (100 * Pi, 20); plot (x, sin (x) +, '-O ', x, 100 + X. ^ 2/20) % plot end axis offset (GCA, 'position', [,]) Set (GCF, 'papersize', []) Set (GCF, 'paperposition', [0.01, 0.01, 7.98, 7.98]) Lim = get (GCA, 'xlim'); Set (GCA, 'xlim', [Lim (1) lim (2) + (Lim (2)-Lim (1)/19]) Lim = get (GCA, 'ylim'); Set (GCA, 'ylim ', [Lim (1) Lim (2) + (Lim (2)-Lim (1)/19]) print ('-dpdf', figname ); dlmwrite ([figname '. dat '], [get (GCA, 'xl Im '); get (GCA, 'ylim'); get (GCA, 'zlim')], ''); % second figure figname = 'fig2 '; % plot peaks (300); shading interpview ([]) % plot end axis offset (GCA, 'position', [,]) Set (GCF, 'papersize ', [8, 8]) Set (GCF, 'paperposition', [0.01, 0.01, 7.98, 7.98]) Set (GCA, 'xlimmode', 'manual ') print ('-dpdf', figname); dlmwrite ([figname '. dat '], [get (GCA, 'xlim'); get (GCA, 'ylim'); get (GCA, 'zlim')], ''); % compile latex document!

There may be a better way to use MATLAB 2tikz to directly convert MATLAB graphics into tikzp/gfplots code. See
