Game developers didn’t have it easy in the 1990s. Because they had extremely limited computing power, they had to write their code as efficiently as possible. Consider the first-person shooter Quake ...

A basic Newton-Raphson type nonlinear equation solver for sparse or dense systems with m functions of n input variables. Is object-oriented. Works with square, under-determined, or over-determined ...

Tensegrity structures are geometric nonlinear systems and statically and kinematically indeterminate structures that require an initial shape-finding procedure to establish a self-equilibrium state.

We’re suckers for good-looking old-school calculators, so this interesting numerical equation-solving calculator by [Peter Balch] caught our attention. Based around the ESP32-WROOM-32 module and an ...

Introduction: In dynamic PET analysis, the time-activity curves (TACs) observed in each tissue exhibit delays that deviate from the expected arterial input. Particularly in the context of Total-body ...

You can use the Phase Plane and Slope Field apps to qualitatively analyze ordinary differential equations (ODEs). Phase Plane app: Analyze two-dimensional autonomous ODE systems. Slope Field app: ...
