application of ‎f‎uzzy bicubic splines interpolation for solving ‎t‎wo-dimensional linear fuzzy fredholm integral ‎equations‎‎

In this paper, firstly, we review approximation of fuzzy functions by fuzzy bicubic splines interpolation and present a new approach based on the two-dimensional fuzzy splines interpolation and iterative method to approximate the solution of two-dimensional linear fuzzy fredholm integral equa- tion (2dlffie). also, we prove convergence analysis and numerical stability analysis for the proposed numerical algorithm. finally, by an example, we show the efficiency of the proposed method.
