哪位ggjj帮着看看,矩阵怎么赋值?
a=sin(0.2i+0.5j)(i=j)否则a=cos(0.3i+0.4j)

哦,谢谢!矩阵a为10维方阵,i,j为下标,当i=j时,其对应值为sin(0.2i+0.5j),否则为cos(0.3i+0.4j),怎么给a初始化,我编的,运行不了...这回学乖了,在线等,再次感谢
#include "math.h"
#include "stdio.h"
main()
{int i,j;
 static double a[10][10];
 for(i=0;i<=9;i++)
  {for(j=0;j<=9;j++)
    {if(i=!j)
    a[i][j]=cos(0.3i+0.4j);
    else
    a[i][j]=sin(0.2i+0.5j);
    }
  }
  for(i=0;i<=9;i++)
  {for(j=0;j<=9;j++)
      {printf("a=%13.7e\n",a[i][j]);
      printf("\n");}
  }
}
