Replace first number of matrix with the next larger value

I have the following matrix:

StrikeMatrix11= [1:10]

Now I want to replace the first number of StrikeMatrix11 with "2" since the second number of StrikeMatrix11 is larger than its first number.

Unfortunatley, my code is a) too complex and b) not working.

Does anyone have an idea how to fix this?

    if StrikeMatrix11(2)>StrikeMatrix11(1)
               StrikeMatrix11(1)=StrikeMatrix11(2);
    else
            for n=1:10
                while StrikeMatrix11(n+1)<=StrikeMatrix11(1)
                      StrikeMatrix11(1)=StrikeMatrix11(1);
                if    StrikeMatrix11(n+1)>StrikeMatrix11(1)
                      StrikeMatrix11(1)=StrikeMatrix11(n+1);
                      break
                end
                end
            end
    end

Best!

v=randi(10,1,10) % Example
idx=find(v(2:end)>v(1),1)+1
v(1)=v(idx)
