Fix LinAlgSVD example code

A typo in the LinAlgSVD example code made the example not compile.

With this fix, the program compiles and runs as expected:

Here is the matrix A:
 0.680375   0.59688
-0.211234  0.823295
 0.566198 -0.604897
Here is the right hand side b:
-0.329554
 0.536459
-0.444451
The least-squares solution is:
-0.669626
 0.314253
