Dear developers:
I have to initialize a large matrix, and the matrix elemens are long expressions. But I found there seems exists a limit for comma initialization in Eigen.
If the matrix is large, and pass too many expression to comma initialization, the compilation will just aborted. For example, using mingw, I got cc1plus.exe stop work. I also tried intel parallel studio, the error is the same.

Here is my source file https://pastebin.com/Fg2i4ASD

I want to know how to successfully compile my source file.

You are abusing the syntax ! I guess those lines have been generated procedurally, then better use a for loop with classical indexed accesses or row-by-row (or column-by-column) init:

Code: Select all

for i
  for j
    A(i,j) = ...;

for i
  A.row(i) << ...;

for j
  A.col(j) << ...;
