 # Here is a pedagogical implementation of PDHG that solves the linear program:
 # ```math
-# \\begin{aligned}
-# \\text{min} \\ & c^\\top x \\
-# \\text{subject to} \\ & Ax = b \\
-#  & x \\ge 0.
-# \\end{aligned}
+# \begin{aligned}
+# \text{min} \ & c^\top x  \\
+# \text{subject to} \ & Ax = b  \\
+# & x \ge 0.
+# \end{aligned}
 # ```
 #
 # Note that this implementation is intentionally kept simple. It is not robust
