Algebra, Topology, Differential Calculus, and Optimization Theory for Computer Science and Engineering Jean Gallier and Jocelyn Quaintance Book in Progress, Approx. 1440 pages (2017) http://www.cis.upenn.edu/~jean/gbooks/geomath.html
Elementary Differential Geometry presents the main results in the differential geometry of curves and surfaces suitable for a first course on the subject. Prerequisites are kept to an absolute minimum – nothing beyond first courses in linear algebra
Partial Differential Equation Toolbox provides functions for solving structural mechanics, heat transfer, and general partial differential equations (PDEs) using finite element analysis. You can perform linear static analysis to compute deformation,
