From: Konda srinivasarao on 30 Jan 2010 15:57 eror on mat lab code ??? Error using ==> sym.double at 29 DOUBLE cannot convert the input expression into a double array. If the input expression contains a symbolic variable, use the VPA function instead. how we converting the symbolic expression to an array.. for example Er=[ 23,56, -89,24,......] this is not an array ,this is solutions of Er, when solving an expression... then how i can convet this into an array, and then iam obtaining the minimum positive value,ignoring the negative values from tha expression........... |
