matlab中Warning:Matrix is singular to working precision.是什么错误,应该怎么解决,最好具体点
>> x=-8:0.01:8;
>> y=-8:0.01:8;
>> [X,Y]=meshgrid(x,y);
>> Z=(sin(sqrt(X.^2+Y.^2)))/sqrt(X.^2+Y.^2);
surf(X,Y,Z)
Warning:Matrix is singular to working precision.

Warning:Matrix is singular to working precision.
你在 Z=(sin(sqrt(X.^2+Y.^2)))/sqrt(X.^2+Y.^2);这句中的除不可以用矩阵的除号“/”啊.要用数组运算的“./”啊.矩阵运算跟数组运算是不同的.
