The following error occurred converting from sym to double:
Error using ==> mupadmex
Error in MuPAD command:DOUBLE cannot convert the input expression into a double array.
If the input expression contains a symbolic variable,use the VPA function instead.

按照提示修改就行了,赋值类型错误了;不知道你的目的,A(:,1)=c*A(:,1)改为B=c*A(:,1)就可行了
