Scilab 5.5.0 after Scilab 5.4.1

From Scilab 5.4.1 to 5.5.0
 Scilab 5.4.1 was stable, 5.5.0 is more stable
– More than 600 bug fxes
– More than 500 tests added
 Scilab 5.4.1 graphics was fast, 5.5.0 is faster
– Evolution of 2D/3D rendering
– Basis of Scilab 6.0 graphics
 Scilab 5.4.1 interface was friendly, 5.5.0 is
comfortable

Application design
 Designing Algorithm
– New functions / blocks (if you want more, just ask...)
– Bug Fixes / Improvements
 Designing GUI
– Diferent way to design/program
– Same rendering
 Designing End-User Application
– More and more ATOMS modules
– Asynchronous life cycle

Application deployment
 Diferent User orientation
– Developer (<= 5.4.1)
• Console interaction
• Develop / Run / Debug
– Operator (beter with 5.5.0)
• No prompt interaction => GUI
• Run / Fill bug reports ?
 ATOMS server
– Dedicated customer side repository

Scilab 5.5.0 answer to users needs

Interaction with other software/language
 JIMS: How to write Java code within Scilab
– Link to existing code / WebServices
 HDF5: Import/Export data from other scientifc
software
– Atmospheric Modeling System / Salome
 Remote File Access:
– Retrieve network data
 HTML: Interact with web pages
– Reporting
– Data feeds

Scilab based application design (GUI)
 Advanced uicontrol capabilities
– New fgure properties
– New design capabilities:
• Absolute positioning (<= 5.4.1)
• Proportional design (normalized)
• Automatic placement (layout)
– Faster component research using path
 New uicontrol components
– Tabs
– Frame (Borders/Scroll/Axes)
– Group

Scilab based application design (GUI)
 What about my old hand crafted GUI ?
– Still working in Scilab 5.5.0
– Creation/Interaction Speed Up
 But if I loved my old application look and feel ?
– UseDeprecatedSkin
 My application does not work anymore
– f.visible = “of” ??

– erf, dawson scaled imaginary error

Scilab new graphic features
 Matplot
– Can manage RGB/ARGB images
– Colors are independent of fgure color map
 Plot automatic margins computation
– Titles
– Axes Labels
– Ticks
 Datatips
 Graphic interaction
