Re: [fricas-devel] There are questions one should not ask...

Clearly "typeOf" can only handle 1 argument, following patch should fix this bug, but I wonder if there are better ways of error handling than "error". diff --git a/src/interp/i-spec2.boot b/src/interp/i-spec2.boot index b82cae83..15249526 100644 --- a/src/interp/i-spec2.boot +++ b/src/interp/i-sp

Re: [fricas-devel] how to integrate a generic function in FriCAS?

You should use F := operator "F" to let the system know that 'F' is a function that can be applied to variables. On Thu, Jul 12, 2018 at 8:07 AM, 'Nasser M. Abbasi' via FriCAS - computer algebra system wrote: > sorry for basic question, but after some search I could find what the > correct

[fricas-devel] how to integrate a generic function in FriCAS?

sorry for basic question, but after some search I could find what the correct syntax is. Some integrals I need to run in Fricas use a generic function as in f(x) in the integrand. For example integrate(F(x)/(sqrt(x)*sqrt(-x + 1)),x) Fricas does not like the above --- (1) ->

If I use the names 'first' and 'last' in a spad file I get a message: Semantic Errors: [1] last is BOTH a variable and a literal [2] first is BOTH a variable and a literal ... What does this mean? In spite of the "semantic error" the code compiles and runs as expected. If

[fricas-devel] [BUG]: draw option unit == [a,b] ignored

Hi, IIC the user guide the draw option unit==[0.2,0.2] should add ticks to the axes x and y, but I cannot see anything. Try eg: draw(sin(11*x),x = 0..2*%pi,toScale == true,title == "Drawn to scale") draw(sin(11*x),x = 0..2*%pi,toScale == true,title == "Drawn to scale and unit", unit==[0.2,0.2
