Description
MathPro is a numerical computing environment and programming language mostly compatible with Matlab. You can implement any numerical method using this program. MathPro is designed in order the user interact more efficiently. Is caracterised by:
- Programs can be viewed or edited using the present famous mobile text editor
- Writing programs more efficiently and solve any mathematical problem.
This Mathematical tool for mobile phones is a Must-have tool for students, professionals and scientists.
MathPro's interface
integrate standard mathematical notation, programming statements, and text in a single worksheet. Is very flexible, fast, and more professional. It runs on handheld mobile devices running java (MIDP 2.0, cldc 1.1).

Comment statements
MathPro comment statements begin with the percent character, %. All characters from the % to the end of the line are treated as a comment.
Flow Control
MathPro supports the basic flow control constructs found in most high level programming languages, the same as in MathLab language.
Branches if constructs
MathPro supports these variants of the ``if'' construct
- if ... end
- if ... else ... end
- if ... else if ... else ... end end
Jumps
return, continue, break
A function may be prematurely left using return.
continue and break are used in loops: continue jumps back to the start of the loop, and begins another cycle. break permanently leaves the loop.
Loops:
For Loops
The for loop allows us to repeat certain commands. If you want to repeat some action in a predetermined way, you can use the for loop. All of the loop structures in MathPro are started with a keyword such as "for", or "while" and they all end with the word "end".
The for loop is written around some set of statements, and you must tell MathPro where to start and where to end. Basically, you give a vector in the "for" statement, and MathPro will loop through for each value in the vector:
While Loops
If you don't like the for loop, you can also use a while loop.
The while loop repeats a sequence of commands as long as some condition is met.
| Programming in MathPro |
| break |
Terminate execution of for or while loop |
| continue |
Pass control to next iteration of for or while loop |
| else |
Conditionally execute statements |
| end |
Terminate conditional block of code |
| error |
Display error message and exit the program |
| disp |
Display error message and exit the program |
| for |
Execute block of code specified number of times |
| if |
Conditionally execute statements |
| return |
Return to invoking function |
| while |
Repeatedly execute statements while condition is true> |
| write |
display text and variables |
| ( ) |
Pass function arguments |
| % |
Insert comment line into code |
| eval |
eval(expression) executes expression, a string containing a valid MathPro expression. see examples 7 and 8 |
| function |
declare a function. see below examples |
