Table of Contents1 将Matlab中公式转化为LaTeX公式1.1 已知公式的转换
'$$\int_0^x\!\int_y dF(u,v)$$' 1.2 未知公式的转换
latex(taylor(sin(t), 16)) 运行结果为:
>> latex(taylor(sin(t),16)) ans = - \frac{t^{15}}{1307674368000} + \frac{t^{13}}{6227020800} - \frac{t^{11}}{39916800} + \frac{t^9}{362880} - \frac{t^7}{5040} + \frac{t^5}{120} - \frac{t^3}{6} + t 结果为字符串类型。 2 将Matlab运行结果的公式显示为适合阅读形式在命令行界面下不是能显示出来适合阅读的公式的,要想显示必须要图形界面下:
text('Interpreter','latex',... 'String','$$\int_0^x\!\int_y dF(u,v)$$',... 'position',[.5 .5],... 'fontsize',16) text(.1,.5,['\fontsize{16}black {\color{magenta}magenta '... '\color[rgb]{0 .5 .5}teal \color{red}red} black again']) text(0.05,0.2,['$$',latex(taylor(sin(t), 16)),'$$'],'interpreter','latex','fontsize',12); 2.1 text函数各个属性

Example ― Using LaTeX to Format Math Equations The LaTeX markup language evolved from TEX, and has a superset of its capabilities. LaTeX gives you more elaborate control over specifying and styling mathematical symbols. The following example illustrates some LaTeX typesetting capabilities when used with the text function. Because the default interpreter is for TEX, you need to specify the parameter-value pair 'interpreter','latex' when typesetting equations such as are contained in the following script: %% LaTeX Examples--Some well known equations rendered in LaTeX % figure('color','white','units','inches','position',[2 2 4 6.5]); axis off %% A matrix; LaTeX code is % \hbox {magic(3) is } \left( {\matrix{ 8 & 1 & 6 \cr % 3 & 5 & 7 \cr 4 & 9 & 2 } } \right) h(1) = text('units','inch', 'position',[.2 5], ... 'fontsize',14, 'interpreter','latex', 'string',... ['$$\hbox {magic(3) is } \left( {\matrix{ 8 & 1 & 6 \cr'...
