I had written some step-by-step numerical programs for my exam,like newton-rafson(1D,2D,3D),rangkota,calculating landa for a matrix and etc. , if there is anyone that has algorithms in this cases,i like to talk about them.
I tried to write such programs because I also need them. However, the lack of functions containing more than one command stopped me. The only way I found to emulate a function in ClassPad is to write a program that returns the answer as a global variable. For example, a simple program
NewtRaph(f,xguess)
implementing the Newton-Raphson method should calculate the root of the function f(x) by using x=xguess as the initial guess of the root. However, the root found cannot be returned to the main program, because a program cannot return anything. So, the program NewtRaph should return the answer by means of a global variable, say "root". After that, you should do a "DelVar root" to delete the global variable, if you do not need it anymore.
I simply refuse to write programs this way. If you have a better way to overpass the problem, I will be happy to know. But I think that there is no such way, bacause of the serious limitations of the ClassPad's basic....

Sorry, but "Landa" is wrong. You must write "Lambda".I had written some step-by-step numerical programs for my exam,like newton-rafson(1D,2D,3D),rangkota,calculating landa for a matrix and etc. , if there is anyone that has algorithms in this cases,i like to talk about them.
What kind of algorithms do you need? What's your major at university or highschool? "Maybe" I can help you.
