In the mathematical subfield of numerical analysis, an I-spline is a monotone spline function. == Definition == A family of I-spline functions of degree k with n free parameters is defined in terms of the M-splines Mi(x|k, t) I i ( x | k , t ) = ∫ L x M i ( u | k , t ) d u , {\displaystyle I_{i}(x|k,t)=\int _{L}^{x}M_{i}(u|k,t)du,} where L is the lower limit of the domain of the splines.
