Illustrating this through your code example: // Define limits Using this method is better than using the diff function because the output array is of the same size as the original one. Both are actually meant to be used in conjunction because the interp function requires the corresponding derivatives for your y values, which you can easily get through the splin function. The former will give you the corresponding first derivative of your array values while the latter will give you up to the third derivative. This elegantly works not only for piece-wise defined functions but also for functions defined numerically by data. This is demonstrated in the following examples:->2+3 ans 5. It also has the ability to define variables and store values in them so that they can be used later.

I accidentally (but fortunately) found the elegant solution to your end goal (and also to mine) of calculating and plotting the derivatives through the SciLab documentation itself via the splin ( ) and interp ( ) functions. name of the function and want to know its input and output arguments and learn how to use it.->help inv Scilab can be used as a simple calculator to perform numerical calculations. (I expect the result 3 3 and not a matrix.) Calculate derivative of f(x) at the positions x Define array x for which the derivative will be calculated. PS: Is this the right place to ask Scilab-related questions? It seems that there are several StackOverflow communities where Scilab-related questions are asked. But what is then the purpose of numderivative? If you don't want to see the result, type a semicolon afterward. Scilab echoes the assignment of the variable x back to you. Type 'x5' - this is the command to create a variable named x and give it the value 5.

Update 1: Maybe I use the wrong function and diff is the way to go. After every command, you always hit the enter key (return key).

Problem: It seems that I do not understand how the argument x works since the result is not a 1D-array, instead, it is a matrix.

My Google-Fu lead me to the numderivative function.

I tried to start small and just use a simple (continuous) function: f(x) = 3*x.

As my end goal, I want to calculate (and plot) the derivative of a piece-wise defined function, see here.

I am a new user of Scilab and I am not a mathematician.

So remember you won't be able to use them if you upgrade your Scilab to the current stable version. The functions mulf and addf are not available on Scilab 6.0.0.You can check that by removing the ( and ) in the example I gave: the result won't be correct. It is important to use addP at each multiplication step to get the correct result.Perform the symbolic multiplication like matrixMulf(t1,addP(matrixMulf(t2,t3))), where t1, t2, t3 are the enclosed versions of your matrices.Enclose every term of each of your matrices with parenthesis using addP().Test code: A = Дisp(matrixMulf(As,addP(matrixMulf(Bs, Cs))))

encolses each element of a in a pair of parenthesis Here I've implemented three functions that together can perform what you want: function s = scaProd(a,b)Д®lseif (max(size(a)) ~= max(size(b))) |. If what you want is to get the symbolic multiplication of two matrix, you'll have to implement such function.
