Here is my setting (Code snippets simplified for illustration purposes):

I have a figure with a legend that uses the LaTeX interpreter.

figure
plot(my_data,'LineWidth',2)
legend('SMO $\sigma = 10^{-3}$','SMO $\sigma = 10^{-2}$','SMO $\sigma = 10^{-1}$', ...
    'HGO $\sigma = 10^{-3}$','HGO $\sigma = 10^{-2}$','HGO $\sigma = 10^{-1}$', ...
    'Interpreter','latex','NumColumns',3,'Location','north')

When exporting the figure as an SVG I change the interpreter to 'none'. This seems necessary to me because I want to use the Inkscape functionality to export SVG's to .pdf_tex (see: here), but when using the LaTeX interpreter this didn't work in my experience.

fig = gcf;  
ax  = gca;
pos = ax.Legend.Position;       % Remember the legend position before the interpreter is changed
ax.Legend.Interpreter = 'none'; % Change the interpreter
ax.Legend.Position = pos;       % Set the remembered position -> Unfortunately, this didn't help
print(fig,'my_figure_name','-dsvg') % Export as SVG

When including the exported figure in my tex project it is rendered using an LaTeX interpreter. Unfortunately, the legend now occupies to much space (as this was needed for all the LaTeX commands during the export).
