Hi. I have a structure array, Data, of size (1 x120). The 5th column of the field Data.Temp contains zeroes. I want to replace these zeroes with a number 20 from Data(30).Temp to Data(60).Temp. Also, I want to replace these zeroes from Data(61).Temp to Data(80).Temp with a number 24. I am unable to perform this operation. I kindly request some help from the community.

[Data(30:60).Temperature] = deal(20);
[Data(61:80).Temperature] = deal(24);

You renamed the field since the original posting.
Also it turns out that the fields contain arrays of data.
for K = 30:60; Data(K).Temp(:,5) = 20; end
for K = 61:80; Data(K).Temp(:,5) = 24; end
