Member Function Documentation
Initialize the converter, given the fixed structure of the matrix.
There, ndim gives the number of rows and columns of the matrix, nonzeros give the number of nonzero elements, and airn and acjn give the positions of the nonzero elements. The return value is the number of nonzeros in the condensed matrix. (Since nonzero elements can be listed several times in the triplet format, it is possible that this value is different from the input value nonzeros.) This method must be called before the GetIA, GetJA, GetValues methods are called.

Convert the values of the nonzero elements.
Given the values a_triplet for the triplet format, return the array of values for the condensed format in a_condensed. nonzeros_condensed is the length of the array a_condensed and must be identical to the return value of InitializeConverter.
