Dear Octave developpers

there is a minor problem with a graphics structure when trying to export with
matlab2tikz. Legends to not seem to go through.
Here is a minimal example leading to the error


clear *
x = linspace(0,10);
figure(1)
plot(x,sin(x),x,cos(x))
legend('sin(x)','cos(x)')
matlab2tikz('testMat2tikz.tex','standalone',true,'width','7cm')


Octave leads to

error: matrix cannot be indexed with {
error: called from
    matlab2tikz>getLegendEntries at line 1137 column 21
    matlab2tikz>drawAxes at line 861 column 33
    matlab2tikz>saveToFile at line 485 column 13
    matlab2tikz at line 337 column 9
    testMat2tikz at line 6 column 1


Matlab generates the tex file with the legends.
