hi this is my homework ı want to sort matrix A from smallest to largest.But I m stuck here .Can you help me ? Ps:I cant use sort,min,max or other functions

clc;clear;
A=[24.3 24.8 24.6 24.0 22.3 21.0 20.5 20.7 18.8 17.6 15.5 17.5 19.0 19.8 21.4]
B=[]  
for i=1:length(A)
    ek=100;
    for i=1:length(A)      
        if A(i)<ek 
            ek=A(1,i)
        end
    end
    B(1,i)=A(i)
    A(i)=[]
end
B

What sorting method do you want to use? Lots of documentation for sorting methods. Lots of pseudocode for the different sorting methods. Pick one and try implementing the pseudocode in matlab. Then tell us which one you picked and ask a specific question.

[Mustafa Yasin Erdogan]

ı dont know how many sorting methods exist in matlab.But selection sort method is suitable for me i think.Thank you for your answer.

Google for "selection sort pseudocode". I think Selection sort pseudocode is an appropriate read. I'm sure that, regardless of the definition of functions, loops and if-statemens and logical operators are allowed.

It is not possible to solve that problem in MATLAB without using any functions. For an explaination see https://www.mathworks.com/matlabcentral/answers/38787-what-can-be-programmed-without-any-built-in-functions?s_tid=srchtitle
