    Problem with the rank of the matrix

    As I am dealing with problems with the concept of graph theory, I can only connect the graph from computed solutions if the rank is 22. For the first example, I can't connect the graph from the computed solutions, therefore the rank should not be 22. For the second example, the rank of the...

    Problem with the rank of the matrix

    the rank should only have the [highlight #FCE94F]maximum value[/highlight] of min(m,n). For example: the matrix of (24 x 52 ) should only have the maximum value of 24, ie rank <= 24.

    Problem with the rank of the matrix

    Thanks for your reply! May I ask how can I call the DGESVD function / use LAPACK ? It shows "unresolved external symbol _DGESVD@64" when the program ran. I am writing the program by the Microsoft Developer Studio. In fact I cannot find this function on it.....

    Problem with the rank of the matrix

    Hey guys, I am writing a program relating the traffic problem. In some parts, I need to calculate the rank of the given matrix (not a square matrix). May I ask any function can be called in fortran to do so? Or what else can I write? Thanks!
