Installation problem on Windows #94
Description
Here is the code and error message I got after installing the latest version of ecos on Windows 8.1 x64. MATLAB version is 8.3 (R2014a).
n = 5;
A = rand(n); b = rand(n, 1);
cvx_begin
cvx_solver ecos % without this line, CVX will use its default solver
variable x(n)
minimize sum_square(A*x - b)
subject to
x >= 0
cvx_end
Calling ECOS 1.0.5: 12 variables, 6 equality constraints
For improved efficiency, ECOS is solving the dual problem.

Optimal value (cvx_optval): NaN
Error using ecos
Internal problem occurred in ECOS while setting up the problem.
Please send a bug report with data to Alexander Domahidi.

It looks like installation itself went fine...
