SPEED: Engineering Scratchpad

It is an equation-based line-by-line interpreter where equations and results are displayed simultaneously. Variable names can be utilized and re-used. Array variable is allowed which enables iterative calculation. It is also equipped with CoolProp library and IAPWS-IF97 water property function. Last, it works on plain ASCII text files which can be read and shared easily with others. Great for on-the-fly, simple to complex engineering calculations. Right companion for solving elementary to practical level engineering problems. Following features are currently supported. - Simple to complex arithmetic calculations - Simultaneous display of equations and results - Variable assignment based connected calculations - Array variable supported - 5 level depth repetition loop - Text output (echo) manipulation - Paraview output of 3D voxel data - 1D, 2D linear interpolation - Plotting - 1D scatter plot - 2D heatmap plot - 3D isometric plot - Histogram - Pie chart - Bar chart - Box plot - Stem and leaf plot - CoolProp fluid property functions - IAPWS-IF97 light water property calculation - Linear equation solver (A*x=b) - Nonlinear solvers - Bisection method - Golden-section maximization method - Particle swarm optimization (PSO) method for minimization - Extensive statistical functions - Various distribution functions - Check for normality - Transformation - Tolerance limit factor - Linear regression - Extensive unit conversion factors - Other useful functions
