pro Fit

Il software Macintosh per analisi di dati, funzioni e modelli matematici

About pro Fit

pro Fit is a Macintosh (Mac OS) application for data/function analysis, plotting, and curve fitting. It is used by scientists and engineers to analyze their measurements and the mathematical models they use to describe them.
Scientists or students can define any mathematical function and use it to model their data, finding by linear or nonlinear curve fitting the function parameters that best describe their observations. Moreover, they can use a number of tools for the mathematical and statistical analysis of functions and data sets, and they can produce esthetically pleasing graphical representations for their scientific reports.

What's new in pro Fit 6.2?

• Built-in Python support. Python within pro Fit is now a full equivalent of pro Fit's traditional Pascal-like language for defining pro Fit programs and functions. Python is a mature programming language with a rich feature set well-suited for scientific computations, and it can tap into a vast choice of scientific libraries, such as numpy and scipy
  
• Extended fitting capabilities. The fitting algorithms have been modified for better convergence and more versatility in multidimensional fitting, and an automatic fitting algorithm runs fits instantaneously when the underlying data changes
  
• Additional data processing tools: New commands for convolution and correlation, revamped sorting capabilities, improved text file import
  
• Performance: Various parts of pro Fit have been optimized for threaded processing and yield improved performance on multicore CPUs
