DADiSP (Data Analysis and Display, pronounced day-disp) is a numerical computing environment developed by DSP Development Corporation which allows one to display and manipulate data series, matrices and images with an interface similar to a spreadsheet.
However, unlike a typical business spreadsheet that operates on a table of cells each of which contain single scalar values, a DADiSP Worksheet consists of multiple interrelated windows where each window contains an entire series or multi-column matrix.
SPL has a C/C++ like syntax and is incrementally compiled into intermediate bytecode, which is executed by a virtual machine.
DADiSP was originally developed in the early 1980s, as part of a research project at MIT to explore the aerodynamics of Formula One racing cars.
[4] The original goal of the project was to enable researchers to quickly explore data analysis algorithms without the need for traditional programming.
