Abstract: The numerical analytical method of spatial cable shape is used to solve the initial equilibrium state accurately, and it is confronted with the high initial value, which is difficult to solve. This paper is based on the Matlab mathematical software fsolve function to write an iterative method for solving. Writing the traditional matrix method to solve the influence matrix method, the comparison results show that the former is of low precision, and it is easy to converge.
