Hello everybody,
I have the followong question.
In a struct I have two cell arrays CellA and CellB. These cell arrays are identically built and contain the information "DataA, DataB, Name"
What I want to do ist to compare the strings of "Name" of both Cell arrays. If they are the same I want to calculate CellA.DataA - CellB.DataA
The calculated values are saved in a third cell array CellC. This is my actual script.
i=length(data.CellB);
a=1;
for k = 1:length(data.CellA)
while a < i
tf = strcmp(data.CellA{k, 1}.Reifen, data.CellB{a, 1}.Reifen);
if tf == 1
data.CellC{k,1} = data.CellA{k, 1}.DataA - data.CellB{a, 1}.DataA;
data.CellC{k,2} = data.CellA{k, 1}.DataA - data.CellB{a, 1}.DataA;
data.CellC{k,3} = data.CellA{k, 1}.DataB - data.CellB{a, 1}.DataB;
data.CellC{k,4} = data.CellA{k, 1}.DataB - data.CellB{a, 1}.DataB;
a=a+1;
else
data.Pegeldelta{k, 1}=0;
data.Pegeldelta{k, 2}=0;
data.Pegeldelta{k, 3}=0;
data.Pegeldelta{k, 4}=0;
end
end
end
But it seems like I´m stuck in an endless loop.
I think the problem is at "a". After the a=a+1 iteration it doesn´t get set back "a" so the loop doesn´t start again at 1 for the next comparison.
Hope you can help me with this.

If you know the number of interations, why not use a for loop again?
for k = 1:size(data.CellA,1) %use size(___,dim) instead of length() to get predictable behavior, use numel if you want all elements
A = data.CellA{k, 1}; %make the code more readable with a temp variable
for a = 1:size(data.CellB,1)
B = data.CellB{a, 1};
tf = strcmp(A.Reifen, B.Reifen);
if tf %don't compare a logical to 1
data.CellC{k,1} = A.DataA - B.DataA;
data.CellC{k,2} = A.DataA - B.DataA;
data.CellC{k,3} = A.DataB - B.DataB;
data.CellC{k,4} = A.DataB - B.DataB;
else
data.Pegeldelta{k, 1}=0;
data.Pegeldelta{k, 2}=0;
data.Pegeldelta{k, 3}=0;
data.Pegeldelta{k, 4}=0;
end
end
end
