is it possible to feed in symbolics as arguments to a function?

I really fucking wish. You can't dynamically assign variable names either.

lame

go back to maple

Actually, reading your question closer... what do you mean by symbolics?

You can do something like this:

%begin script.m
foo1 = 3;
foo2 = 5;
[output1,output2]=functionname(foo1,foo2,third_argument);
somenewvalue=output1+output2;
%end of script

^yeah, i was going to say, you can use variables in function as function arguments. assuming all dimensions line up, you can use matrices, arrays, structures, etc as function arguments as well.

i meant something like

%begin script.m
syms d, theta;
foo1 = d;
foo2 = theta;
[output1,output2]=functionname(foo1,foo2,third_argument);
somenewvalue=output1+output2;
%end of script

as long as d and theta have been defined, then yes. i'm not aware of any general symbolic equation solving. but i don't use it for that so . . .

is there a way to solve for multiple variables in matlab?

like if you have

cos(x+y) - sin(z), to return a range of values for x, y,and z?

indeed there is!

[xx, yy, zz] = solve('cos(x+y) - sin(z)=0', 'x, y, z')

also, god bless the simple() command

also, to my original question, yes there is
