MATLAB: Merging Arrays in Ascending Order

arrayfor loopmergeswap

Hello, I am new to matlab. I have this problem. I have to merge two or more arrays into a new array in ascending order for example

The size of the new array will be equal to the sum of all the input arrays.

INPUT :

a = [1 2 3 5 6 8 9 ]
b = [4 7 10 15 17 20 ]
c = [11 12 13 14 16 18 19]

OUTPUT:

d = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20]

Hello my friend, I'm new too.

I guess you can use:

d = [a b c]

then sort:

d_sort = sort (d)

MATLAB: How to sort an array of structures based upon a particular field in MATLAB

The ability to use SORT with a structure array is not available in MATLAB.

As a workaround you can modify the following code that sorts an array of structures based upon a numeric first field:

%%Create dummy struct array
a.n=1;
a.name='a';
b.n=3;
b.name='b';
c.n=2;
c.name='c';
array = [a b c];
%%Sort the array
cells = struct2cell(array); %converts struct to cell matrix
sortvals = cells(1,1,:); % gets the values of just the first field
mat = cell2mat(sortvals); % converts values to a matrix
mat = squeeze(mat); %removes the empty dimensions for a single vector
[sorted,ix] = sort(mat); %sorts the vector of values
array = array(ix); %rearranges the original array
