You could do this using conv without loops avg_2 = mean([A(1:end-1);A(2:end)]) avg_4 = conv(A,ones(1,4)/4,'valid') avg_8 = conv(A,ones(1,8)/8,'valid') Output for the sample Input: avg_2 = 0.8445 5.9715 -0.6205 -3.5505 2.5530 6.9475 10.6100 12.5635 6.4600 avg_4 = 0.1120 1.2105 0.9662 1.6985 6.5815 9.7555 8.5350 avg_8 = 3.3467 5.4830 4.7506 Finding Standard Deviation...

Incrementing an integer and initialisation placement having a weird effect?
You are causing undefined behavior in scanf("%s", &c); because "%s" specifier adds a terminating nul byte to the target which is a single char. Instead you can try if (scanf(" %c", &c) != 1) handleErrorPlease(); the space before the "%c" is intentional, it will eat any white space character left...
Infinite loop with fread
If you're "trying to allocate an array 64 bytes in size", you may consider uint8_t Buffer[64]; instead of uint8_t *Buffer[64]; (the latter is an array of 64 pointers to byte) After doing this, you will have no need in malloc as your structure with a 64 bytes array inside is...
Check for new files in a loop - java
Rather than comparing old and new files, why not write a method to just return Last Modified Files. public static ArrayList<File> listLastModifiedFiles(File folder, long sleepDuration) throws Exception { ArrayList<File> newFileList = new ArrayList<File>(); for (File fileEntry : folder.listFiles()) if ((System.currentTimeMillis() - fileEntry.lastModified()) <= sleepDuration) newFileList.add(fileEntry); return newFileList; } //Sample usage:...
How to retrieve filtered data from json with double for loop
javascript,json,loops,for-loop,filter
If i understood you correctly, you need to add additional for loop for all bussen for (var i=0;i<bushalte2.length;i++) { $("#bussen").append(bushalte2[i].name + "<br/>"); for (var j=0; j <bushalte2[i].bussen.length; j++) { $("#bussen").append(bushalte2[i].bussen[j].busnummer + "<br/>"); } } here is updated jsfiddle https://jsfiddle.net/or4e8t3u/...
R - Check different matrices with a possible lag
Here's a simple way to do it: lag <- 3 # or whatever lag you want nr <- nrow(mat1) nc <- ncol(mat1) mat3 <- matrix(0, ncol=nc, nrow=nr) for (r in 1:nr) { for (c in 1:nc) { if (mat1[r,c] == 1 && any(mat2[r,c:min(c+lag,nc)] == 1)) mat3[r,c] <- 1 } }...
printing an string in cross manner using c program
c,arrays,loops,for-loop,multidimensional-array
In your code, you need to change the for loop condition checking expressions, like i == lenstr and later i==0. They are not entering the loop, essentially. Instead, you can replace the whole block for(i = 0;i == lenstr;i++) { str2[i][j] = str[i]; j = j + 1; } for(i...
How to iterate through a table in its exact order?
You may utilize integer part of the table to store keys in order: function add(t, k, v, ...) if k ~= nil then t[k] = v t[#t+1] = k return add(t, ...) end return t end t = add({ }, "A", "hi", "B", "my", "C", "name", "D", "is") for i,k...
while loop is not breaking even if the condition is satisfied
You are using same variable (i) for both loops, and in the inner loop the condition of exit is i being 0 or negative, but the only change in this variable in the inner loop is i=i/10 which usually gives unexpected results when using with int. Also, the i will...
How to incrementally iterate through all possible values of a byte array of size n.
In case you don't realize: 16 bytes is the size of a Guid or the size of a standard cryptographic key size. There are so many combinations that you cannot enumerate even a fraction. Maybe you can enumerate the last 8 bytes if you parallelize across 1000 machines and wait...
