I have been using SSE/ SIMD Matrix multiplication approaches and I persistently get this error:

The code almost never throws the error when matrices are size NxN, N =4.
Also, I have a 4 core laptop with 2 GB RAM and I am using VS2013.
When I am giving elements for row 2 ,program crashes .it says access violation.

I wrote a sequential matrix multiplication program in c.
After execution i get error like

i want to know how i can solve this question? do i need to create a class or write the program codes.

ublas::matrix<int> A(8,5);
ublas::matrix<int> B(2,5);
for(size_t i=0;i<A.size1();++i)
for(size_t j=0;j<A.size2();++j)

ublas::matrix_range<ublas::matrix<int> > a(A,ublas::range(0,2),ublas::range(0,5));
a=B;
and it works.
but if the matrix is compressed_matrix type, there's something with it. the error log as below:

First line shows row and column number
First index of the second line tells the number of non-zero entries of the first row and second index tell the column number where the non zero entry is placed
for 1st row of matrix:
non-zero entries=2
column number=1
non-zero entry=3
column number=2
non-zero entry=2
covert this in the given form

I have a 3x3x3 matrix with values hanging from 1 to 27.
The order is this: Code: m[0][0][0] = 1;
m[0][0][1] = 2;
m[0][0][2] = 3;
m[0][1][0] = 4;
m[0][1][1] = 5;
m[0][1][2] = 6;

Is there an easy way to compute the indexes given the value? For example, I know that the first index can be found by dividing the value by 9.0: Code: const int firstIndex = ceil(value / 9.0) - 1; What about the second and the third indexes? I couldn't find a pattern in the numbers, and I didn't want to iterate through the matrix (the indexes will be calculated many times).
The other option is to create arrays where the values will be indexes and the matrix indexes will be the values. I'm not sure if it is the best way though
I wants to print matrix such that Consider that original matrix look like following

we can use only two for loops.
I'm writing a function that inserts a row into a matrix and deletes the last row.
But I'm having trouble. What do I need to add to this function:

88 110 145 90 90 90 90
77 85 130 55 210 122 200
// the row :
152 152 149 155 170
// matrix after adding the previous row :
12 5 35 35 35 65 170
48 15 190 85 27 27 24
100 315 119 600 116 129 70

77 85 130 55 210 122 200

The method doesn't work properly, the point of the code is to tell the minimum value in the given matrix "m", it's supposed to take the first value of the matrix store it in min_ and then compare it to every value of the matrix, if the value stored in min_ is bigger than the current value in the loop then it's stored as the new min_ and at the end it's supposed to print that minimum...
