Update makeCacheMatrix.R

creating matrix by passing values to the arguments of function makeCacheMatrix(m,r,c)where m is a matrix, r is for number of rows and finally for c is number of columns. We have to pass the values like this at Coomand prompt -  > cm <- makeCacheMatrix(c(3,3.2,3.5,3.6),2,2)  
cm$cacheSolve()
