I NEED HELP WITH THIS PROBLEM!!!! ANYONE!!!!
/*3. Write the function: double max_norm(double *v, int n) to compute
the maximum norm of vector v[] with n elements. The max norm of a vector is
computed by taking the maximum absolute value of its elements.
In prob3() compute x1[]=a[][]*x0[], call max_norm() to compute the max_norm
x1[]. In order to normalize (or convert it to a unit vector), divide each
element of x1[] by the norm. Print the normalized x1[] using %12.4e. Then
copy x1[] as x0[] (to perform updating) and repeat the process nine more times
. */
double a[5][5]={ 1.0, 0.2, 0.6, 0.3,-0.2,
0.2, 3.0,-0.1, 0.2, 0.7,

Exactly, where are you having problems with?
Be more specific and post relevant portion of code you have tried already and it is not working.

I'm completely lost....I don't understand how to write the first function then call on it???
...then ask your teacher to divide your homework grade by 2 and send the second half to the author of the best answer...
