Its also described here nicely
http://distance-ed.math.tamu.edu/Math64 ... node6.html

But it also says that there are methods for accelerating convergence of the QR method.

Could you point to me where it is explained on how to accelerate convergence of QR method?

Hi,
I have written a code for Matrix Inversion. Its working fine for the small samples. But I want to test for more datas.
Could you give me the source from where I can get test data?

i m doing like this #define MAXROWS 100 float *arr[MAXROWS]; //read no of rows & cols from user for(i=0=i<rows;i++) arr = (float *)malloc(col * sizeof(float)); Here I can have rows at the max MAXROWS. Is it possible to have dynamic allocation of memory without knowing/declaring the maximum no of rows?

Hi,

Code: Select all

#include<stdio.h>
#include<stdlib.h>


main()
{
	int i,j;

	for(j=0;j<10;j++)
	{
		i = rand();
		printf("\n%d",i);
	}
}

I am running this in Microsoft Visual C++.
The problem is I am getting same set of values everytime I run ... what should I do to get different sets of value ?

Why am i getting wrong answer??? #include<stdio.h> #include<stdlib.h> int which_time_group( int a ); float func(char ch,int *u1,int *u2,int *u3,float R[][3],int lt[],int ut[],int a,int b,int c,int d); main() {int a,b,c,d,ph1,ph2,lt[3],ut[3]; int u1,u2,u3,i=0; float amnt; char ch; float R[5][3]; R[1]...

i have tried what adrian has said....but still error.....
my p is 4357186184021382204544

but my prog output is 4357186184021382004736

the difference is in the last few digits......
i have noticed that i had forgotten & in scanf earlier but this time i did what adrian had told me..

#include<stdio.h> #include<stdlib.h> void func(int N); main() {int N; do{ scanf("%d",&N); if(N == 0) exit(1); if(N==13) { printf("1\n"); continue; } /* printf("N = %d\n",N); */ func(N); }while(N != 0); } void func(int N) {int m; int check(int m,int N); for(m=1;m<=N;m++) if( check(m,N) == 1) { print...

i m stiil getting error my p is 4357186184021382204544 when double p; scanf("%Lf",p); printf("%0.0f",p); ANS is 0 when double p; scanf("%Lf",p); printf("%0.0Lf",p); ANS is 280585630299556481757617220275852364727636170628410927600364713659709368033262555286057473837891584000 when double p; scanf("%lf...

I couldn't underwstand why i should i think the way tiwari ji has told me..... My prog is acting acoording to the input..... Even if what tiwari ji has told is true i don't see where my prog contradicts his argument....... Can any one give me a sample input where my prog fails to run..... i have alr...

The problem is still there whether i use %lf or %Lf

I m unable to read the long sample input.

taj79

But my problem is reading p when it is big.

Code: Select all

#include<stdio.h>
#include<stdlib.h>

main()
{int d;
 long double p;
 scanf("%f",p);
 printf("%0.0f",p);
}

For the sample input I m failing to read the input.....[/code]
