居中图形问题

Question

我对 Latex 还不熟悉，在将 MATLAB 中的图形居中时遇到了一些困难。如您所见，MATLAB 中的代码在 Latex 上打印得很完美，图片也是如此。但是，我使用了，\centering但\begin{center}没有成功。

\documentclass[12pt]{article}%For type of paper
\usepackage{authblk}%For author commands
\usepackage{setspace}% For double space
\doublespacing% For double space
\usepackage{subeqnarray} % For number equations (1a), (1b) etc.
\usepackage{graphicx,epstopdf} % For including graphics
\usepackage[framed , numbered]{matlab-prettifier}% For MATLAB code
\usepackage{amssymb}% For ams math, symbol packages
\usepackage{amsmath} % For more ams
\usepackage{nccmath}% For adding Mathematical commands
\usepackage[english]{babel}
\usepackage{blindtext}
\usepackage[a4paper,margin=2.5cm]{geometry} % set page margins as needed
\newcommand{\diff}{\mathop{}\!d}

\begin{document}
\begin{figure}[h]
\includegraphics[width=1.50\textwidth]{fourierSeries.eps}
\centering
\end{figure}
\lstinputlisting[style = Matlab-editor]{fourierSeries.m}
\end{document}

以下是来自 MATLAB 的代码：

function [ao,a,b] = fourierSeries(f,T,N)
  syms t;
  T = 2;
  wo = 2*pi/T;
  % heaviside(x-k) when k = 1, heaviside(x-1). it shifts the graph to the right.
  % when k = -1, for example, the graph is shift to the left.
  f = heaviside(t) - heaviside(t-1); 
  ao_sym = 1/T* int(f,t,0,T);
  ao = double(ao_sym);
  for n = 1:N;
    a_sym(n) = 2/T*int(f*cos(n*wo*t),t,0,T);
    b_sym(n) = 2/T*int(f*sin(n*wo*t),t,0,T);
    
    a(n) = double(a_sym(n));
    b(n) = double(b_sym(n));
  end
end
