Version history

    MatBasic v1.1:

*

Some minor changes in debugger;

*

Multiple inner changes of interface;

+

Pointers at functions are added, fast call is acceptable;

+

Identifier type is added;

+

Raising to the power operator ^ is applicable for matrix arithmetic;

+

New commands "continue", "goto" and "input" for console are added;

+

Over 50 new functions from different topics, and sorting.

    MatBasic v1.2:

*

Some major bugs fixed;

*+

Major changes in expressions syntax analysis engine. An operations priority now is correctly and arranged. Speed optimization up to 15-30%;

*

Raising to the power ^ operation priority is now higher than that of unary operations -,+,!. That is expression -2^2, is now equal -4;

*

Major changes in complex arithmetic, trigonometry and many basic functions (sqrt, log, and more etc.). Calculation now is more reliable and its precision is increased;

*+

Major changes and addition of functions of linear algebra;

*

Multiple minor changes and small bugs fixed;

+

Tool tips is showing program data state;

+

Postfix operation of matrix transposition and complex conjugation ';

+

Element-by-element variants of multiplication, division, raising to the power, conjugation. .*, ./, .^, .';

+

Fast or short circuit logical operations && || with optimization;

+

Changing (addition) of operation excluding "OR" ~;

+

Add-on to the operation of vector generation ... Adding of a step setting (e.g. a=1..0.1..10);

+

Multiple indexation or extraction of submatrices. E.g. for extraction of a second row from 3x3 matrix X: y=X[2,1..3];

+

Major changes of a functions declaration and usage. Added some default parameters, functions with a variable number of arguments. Every function can be overloaded.

+

Now returnable matrices can be assigned directly. E.g. the following is possible: [L,U,P]=lu(X);

+

Over 80 new built-in functions;

+

New command "pause";

+

Full context-sensitive help is added;
