Hello

1) In some countings I have to find max or min value from, for example, 3 defined earlier definitions. After using max (min) function SMath is not showing results, but information that max (min) function has been not defined. What's even stranger - when I put my cursor over the definition of max (min) function it shows me inserted values.

Some screen shots (I'm using the Polish version, but on the second screen information is saying that function is not definied):





Is it bug or maybe I'm doing something wrong?

2) Is it possible to change default font?

SMath is the only alternative for the MathCAD - thank You a lot for creating and developing it. Keep up the good work

Best regards
Mateusz

Hello, Mateusz

This restriction of "min" and "max" functions is not such a problem. Here is some possibility
a1←2
a2←5
a3←3
min(augment(a1;a2;a3))=2
or
a←mat(a1;a2;a3;3;1)
min(a)=2
Here is a bit more complex problem. Minimal element from two matrices?
b←mat(3;-2;4;1;2;2)
c←mat(3;4;1;-6;5;1;2;2;1;3;3)
min(augment(min(;min(c)))=-6
As the matrices have different numbers of rows and columns, you can not "augment" or "stack" them to make a single matrix. Let's try to make a single "blocked" matrix.
d←mat(b;c;2;1)
d=mat(mat(3;-2;4;1;2;2);mat(3;4;1;-6;5;1;2;2;1;3;3);2;1)
This will not work
min(d)=#
Type conversion error! But there is a solution
min(augment(min(el(d;1;1));min(el(d;2;1))))=-6
or
min(stack(min(el(d;1;1));min(el(d;2;1))))=-6

I think it is not so complicated as it seems to be.
