Kalender Puasa 2018

Dari Abu Hurairah ra., bahwa Nabi shallallahu alaihi wasallam bersabda:

Demi Dzat yang jiwa Muhammad berada di tangan-Nya, sesungguhnya bau mulut orang yang berpuasa lebih harum di sisi Allah pada hari kiamat daripada bau misk atau kasturi. Dan bagi orang yang berpuasa ada dua kegembiraan, ketika berbuka mereka bergembira dengan bukanya dan ketika bertemu Allah mereka bergembira karena puasanya.”

(HR. Bukhari dan Muslim)

Muslim Fasting Calendar 2018

The Prophet Muhammad , peace be upon him, said :

By Him in Whose Hands my soul is, the smell coming out from the mouth of fasting person is better in sight of Allah than the smell of musk. (allah says about the fasting person), “He has left his food, drink, and desires for My Sake. The fast is for Me. So I will reward (the fasting person) for it and the reward of good deeds is multiplied ten times.”

^reference : Sahih al-Bukhari 1894^

So , I present to, especially myself, my brother, and sister as a reminder this Muslim Fasting Calendar 2018 which can be obtained in this repository or simply download at :

Matrix Construction in C++ using Armadillo

As a follow-through of vector, we go on matrix construction. Starting from the definition, matrix is a rectangular array of numbers, symbols, or expressions, arranged in rows and columns. The individual items in an $m \times n$ matrix $A$ often denoted by $a_{ij}$ or so-called elements, where $i$ is row index and $j$ is column index.

Because of there is no container for matrix in C/C++ standard library, let’s make our way construction matrix. In C we could use pointer of array or pointer of pointer as follows :

int m = 4, n = 3, i;

// Using pointer of array
int *B[m];
for (i = 0; i < m; i++) {
    A[i] = (int *) calloc(n, sizeof(int));
}

// Using pointer of pointer
int **B = (int **) calloc(m, sizeof(int *));
for (i = 0; i < m; i++) {
    B[i] = (int *) calloc(n, sizeof(int)); 
}

Vector Construction in C++ using Armadillo

A collection of data in a row (or column) which may be summed together, multiplied by number, and having the same type (for instance real number, integer, complex number, float) is called vector. In programming, we tend to be familiar with array. Either in mathematics or programming, vector is accessed using index. For example, assume we have a vector $\mathbf{v}​$ that comprise $v_1​$, $v_2​$, $v_3​$, and so forth. Alternatively,

$$\mathbf{v}=v_1 \hat{i} + v_2 \hat{j} + v_3 \hat{k}$$
