## [Scilab-users] Double and triple integral query

 Hello all,I have looked at the int2d and int3d commands for double and triple integrals, but was wondering if there was a simple method of defining the input triangles or tetrahedrons (int2d and int3d respectively)?It would be nice to just specify the function, limits and integration variable(s) e.g.:double_integral (f(x,y), var_x, lower_x, upper_x, Var_y, lower_y, upper_y) etcThanks for any pointersLester _______________________________________________ users mailing list [hidden email] http://lists.scilab.org/mailman/listinfo/users

Do you mean something like meshgrid() but that would generate triangles? https://help.scilab.org/docs/6.0.2/en_US/meshgrid.html-- Christophe Dang Ngoc Chan Mechanical calculation engineer General This e-mail may contain confidential and/or privileged information.

 Hello, Generating a 2d triangular mesh will be possible in 6.1 version, see https://codereview.scilab.org/#/c/20681/S.
