WebbRatmath. Ratmath is a collection of utilities for working with rational numbers, approximations, and intervals in Common Lisp. Functions are included to calculate the closest single approximant given a maximum numerator/denominator (rat) or the smallest bounded rational interval (infsup).The infsup function can find the floating point … Webb20 okt. 2016 · I suspect this is related to the transfer of an object of type infsup. You could check this as follows: x = infsup(1,2); save tmp x. clear. load tmp. x * 2; If that fails in the same way, then the problem lies with the class infsup. If that succeeds, then I'm not sure where the problem lies... WebbFunction names are based on IEEE Std 1788-2015, IEEE standard for interval arithmetic, and support for more functions can easily be added in plugins (see below). Operands and results are either intervals, numbers, boolean values or arrays. Intervals may be given in hexadecimal notation. sleep powerpoint background

Webb3 juni 1993 · We briefly review the inf-sup condition for the finite element solution of problems in incompressible elasticity, and then propose a numerical test on whether the inf-sup condition is passed. The evaluation of elements with this test is simple, and various results are presented. This inf-sup test will prove useful for many discretizations of ...
