There may be a mistake in your original question as I don't understand mathematically the '200/Increment1+1' partĪs said by you should not think with for loops but more with linear algebra like K=(5/9)*(F+459.67) wich translate to : take the vector F, add 459.67 to each element, and multiply that by 5/9Īlso be aware that x=x' (as suggested by Rohan) computes the transpose conjugate of a matrix/vector. Indeed, the step between two element of F is (end-start)/(number-1) so you could also write F=0:200/(Increment1-1):200. So if you wish Increment1 elements as suggested, you would have to write F=linspace(0,200,Increment1). (See also the section called Flattened Matrix Representation.In scilab there's two way to define a vector : using the step as in x=start:step:end or the total number of element as in x=linspace(start,end,number) It comes in four different guises.Ī (hyper-)matrix can be reshaped with the Largest elements from all argument matrices.

To the full matrix size, like scalmat = scal The matrices must be compatible, scalars are expanded With more than one matrix or scalar as arguments. These forms return the maximum values of each row orĬolumn along with the respective indices of the Theįorm of the index vector is the same as for Returns the position of the maximum element, too. Matrix are so common that Scilab has separate Searching the smallest or the largest entry in a To get the number of elements that match a criterion, Perfectly OK on the left-hand side of an assignment.

We summarize the timing results of a PII/330 Linux-system in Table 6-1.Įxample 6-1. Good as it can get? No, the standard scalar product is not only aīuilt-in function it is also an operator: s = a * b' One obvious advantage is that we have a one-liner now. The section called Functions Operating on a Matrix as a Whole.) s = sum(a. Modified, but we can replace it with the element wise Previous examples the expression in the loop body has not been OK, it is time for a really fast vector operation. So, only line 3 is re-evaluated in each round trip. Line 2 is only interpreted once the vector i =ġ:n is set up and the loop body, line 3 is threaded over The first step to get some vectorization is to replace the Other hand it uses only very little memory memory as no vectors The example utilizes no vectorization at all. Here Scilab re-interprets lines 3 to 5 in every round-trip, which Naive as we are, we start with s = 0 // line 1 Say we want to calculate the standard scalar product Let us explain that with a simple example. Interpreter and instead make use of the built in vectorized The key to achieve a high speed with Scilab is to avoid the
