如何使用 LaTex 将我的图形排列成自定义矩阵的形式？

Question

我有三个图：a.eps、b.eps 和 c.eps

我该如何像下面这样排列我的图形，以便以后将它们称为图 1 (a) 等等？我可以调整 a、b 和 c 的高度和宽度吗？

This figure shows the drag force $D$ versus the scaled mass $M$ for various values of the ratio between the inertia $I$ and the mass $M$, i.e. for various values of $R=\frac{I}{M}$. Here $g=10$ and $A=0.7$. (b) As for (a) but with $A=0.5$. (c) As for (a) and (b) but with $A=0.25$.}
