Programming

'''SMath Studio''' has several programming commands, so you can write procedures.

Besides what is below, there are also '''Tutorials on programming in SMath Studio: [{UP}Tutorials%2fProgrammingWithSMathStudio.pdf|pdf] | [{UP}Tutorials%2fProgrammingWithSMathStudio.zip|zip] '''

These are '''[[if]]''','''[[for]]''', '''[[while]]''' and '''[[line]]'''.

Take care that some complicated programming structures are not implemented.

{BR}'''If your loops are running too slowly use [[eval]] to speed them up.''' I've got one program that is 500 times faster using eval. 

'''You can often gain a speedup by setting the Optimization mode to Numeric''' as follows: 

1. Let's start with nothing selected:

2. Left-click anywhere on the loop in question. <esc>&nbsp;</esc>The loop will be surrounded by a selection box:

3. Right-click anywhere on the loop. <esc>&nbsp;</esc>The context menu will now have a setting for Optimization. <esc>&nbsp;</esc>Set this to "Numeric." <esc>&nbsp;</esc>The Optimization setting automatically applies to all operations within the selection box.

4. When you left-click outside the loop, SMath Studio will recalculate the page (if you have main-menu option '''Calculation > Auto calculation''' turned on). <esc>&nbsp;</esc>The calculation will typically be faster than it was with Optimization set to Symbolic.
