Get Column Name if matrix row value is 1

Im creating a labeling for x axis of a graph that track change in value based on first row of a matrix as basevalue.
I had managed to code until validmatrix array but i dont know how to extract table label if valid index is "1".
validindexarray determines what element changes per row and the "parameterlabel" is the label name of the table. If validndex is 1 then desiredresult will get the parameter label from the table.
Thanks for your help.
parameterlabel={ 'A' 'B' 'C' 'D' 'E'}
parametervalue=[ 1 2 4 5 3; 2 2 4 5 3; 1 2 5 5 3; 1 2 3 5 2]
validindex= [0 0 0 0 0; 1 0 0 0 0; 0 0 1 0 0; 0 0 1 0 1]
%%My code until here↑↑↑↑
%Need help beyond this line↓↓↓
desiredresult={'','A 1→2','C 4→5','C 4→3 ,E 3→2 '}
xticklabels(desiredresult)
xticklabels({'','A 1→2','C 4→5','C 4→3 ,E 3→2'})

First download Jos's excellent runindex:
Data:
L = {'A','B','C','D','E'};
P = [1 2 4 5 3; 2 2 4 5 3; 1 2 5 5 3; 1 2 3 5 2]
X = [0 0 0 0 0; 1 0 0 0 0; 0 0 1 0 0; 0 0 1 0 1]
Method:
Z = cell2mat(cellfun(@runindex,num2cell(X,1),'uni',0));
[R,C] = find(X);
V = 1:nnz(X);
F = @(r,c)sprintf('%s %d->%d',L{c},P([r-Z(r,c),r],c));
D = arrayfun(F,R,C,'uni',0);
G = @(s)s(3:end);
H = @(d){G(sprintf(', %s',D{d}))};
D = accumarray(R,V(:),[],H);
D(cellfun('isempty',D)) = {''}
Giving:
D =
''
'A 1->2'
'C 4->5'
'C 4->3, E 3->2'
