I created a minimal working example in Matlab:

[x,y] = meshgrid(-2:0.1:2,-2:0.1:2);

fx = x.*y;

fy = x.*y;



figure

quiver(x,y,fx,fy)



matlab2tikz('plot.tex');

This works great and creates the plot.tex document.

So now I included the file in my file

documentclass{article} 

usepackage{pgfplots} 

pgfplotsset{compat=newest} 

pgfplotsset{plot coordinates/math parser=false} 

newlengthfigureheight 

newlengthfigurewidth 

usetikzlibrary{arrows.meta}

begin{document} 

input{plot.tex} 

end{document}

When compiling i get the following errors:

(plot.tex

LaTeX Font Info:    External font `cmex10' loaded for size

(Font)              <7> on input line 1710.

! Package PGF Math Error: You've asked me to divide `0.0' by `0.0', but I canno

t divide any number by `0.0'.



See the PGF Math package documentation for explanation.

Type  H <return>  for immediate help.

 ...                                              



l.1710 end{axis}



This error message was generated by an errmessage

command, so I can't give any explicit help.

Pretend that you're Hercule Poirot: Examine all clues,

and deduce the truth by order and method.



! Arithmetic overflow.

pgfmathdivide@ ...pgfmath@x byc@pgfmath@counta 

                                                  else ifdim 0pt>pgfmath@...

l.1710 end{axis}



I can't carry out that multiplication or division,

since the result is out of range.



! Undefined control sequence.

pgfplotsaxisvisphasetransformpointmeta ...@trafo

l.1710 end{axis}



The control sequence at the end of the top line

of your error message was never def'ed. If you have

misspelled it (e.g., `hobx'), type `I' and the correct

spelling (e.g., `Ihbox'). Otherwise just continue,

and I'll forget about whatever was undefined.

I don't know why this is occurring.

I'm grateful for every help:)
