Spline curves defined in the space constructed by polynomial and hyperbolic functions are studied in this paper . the main research contents and achievements are as follow : firstly , we generate the cardinal extended complete chebychevian ( ect ) - systems on the space constructed by polynomial and hyperbolic functions , then introduce the algebraic - hyperbolic b - spline space and identify the dimension law and zero properties . the existence of a basis of splines with minimal compact supports is demonstrated , and functions named non - uniform algebraic - hyperbolic b - splines are obtained by solving certain linear equations with a block matrix
