Encoded convolutional code is produced by matrix multiplication of input and the generator matrix (1) (2) g g вЋ§вЋЄ = вЋЁ вЋЄвЋ© =.Terdapat tiga algoritma yang biasa digunakan, yaitu bahasa natural. Contoh Pseudocode - Pseudocode adalah bagian dari algoritma yang bertujuan untuk memahami alur logika dari suatu program.Then the blocks are stored in auxiliary memory and their products are computed one. The matrices are partitioned into blocks in such a way that each product of blocks can be handled. However, it is also useful in computing products of matrices in a computer with limited memory capacity. Block multiplication has theoretical uses as we shall see.+ should be allowed as a synonym.Pseudo-code: Load (colA, valA) Pairs One warp per row of A (coalesced loads): Each thread keeps its pair (colA, valA) in registers A.cols: вЂ¦ A.vals: вЂ¦ warpId = threadIdx.x / WARP_SIZE laneId = threadIdx.x % WARP_SIZE aColIt = A.rows + laneId aColEnd = A.rows colA = aColIt < aColEnd ? A.cols : -1 It makes sense that + should be allowed because vector addition is defined to be elementwise addition, but I think that. On the other hand, to add arrays, you must use + without a dot. The same thing happens with division as with multiplication indeed it is worse because there is no mysterious error message, just a mysteriously incorrect graph at the end. I think it would be a simple but major improvement to Matlab if it offered the suggestion вЂњ Perhaps you meant. Since my students do not yet know about matrix multiplication, it is hard to explain this to them. Our 41-element array x is interpreted as a matrix, which cannot be multiplied by itself (because matrix multiplication is only defined if the number of columns of the first matrix is equal to the number of rows of the second). Without the dot, * means matrix multiplication. If you leave out the dot, which is a common mistake for beginners, then you get a hard-to-understand error message: So this is one of those situations where you have to alter the scalar code slightly to work elementwise on arrays. This indicates that we want to apply the multiplication operation elementwise. Plot(x, y) plots a graph of the points with coordinates given by the first argument and coordinates given by the second argument, then joins them up with straight line segments. * x multiplies each element of x by itself, putting the result in a new array y. I am not sure if that is easier terminology or not the fact that, for Matlab, arrays and vectors are the same is crucial at one point later on. The teaching material I have calls this a vector rather than an array. X = -2 : 0.1 : 2 creates an array x containing the 41 elements. This displays a graph of the function for. I worry that for beginning programmers, the fact that elementwise array operations look so similar to scalar operations makes it difficult to understand when these alterations are required - it would be better to consistently require a syntax meaning 'perform this operation elementwise.' Elementwise multiplicationД¬onsider the following piece of code, which is the first example in my Matlab course. If scalar code would always just work elementwise on arrays then I might be happy with this (but I worry that if you had such a language, how would you distinguish operations that act on an array as a unit, not just elementwise?).Д«ut sometimes you need to alter things slightly to work elementwise on arrays. These are very important in Matlab, and sometimes you can write code that looks like it is acting on scalars and it just works elementwise on arrays. applying the same operation to every element of an array). My complaint concerns elementwise operations on arrays (i.e. Today I am going to rant about the first bit of code in our Matlab course (and probably the first non-trivial bit of code in many Matlab courses and tutorials). I don't much like the Matlab language, but then I am unhappy with pretty much every programming language I have ever used except C (which is great for some purposes but they do not include numerical work). I have to teach some simple use of Matlab to my engineering students. Matlab rant: Elementwise operations on arrays
