Your script Trial1.m (attached) is pointlessly complex, and using eval to access variables names just complicates things even more for no benefit. I doubt that this approach is worthwhile. Most of the first half can be replaced with just one line of code, and the second half is an inefficient use of eval to create lots of variables: keep your data in arrays and just use indexing!
Replace all of this:
load('unitCommData.mat','T','loadProfile');
load('DA_price.mat');
nHours = 24;
nIntervals = nHours*4;
DAPrice = zeros(nIntervals,1);
cnt = 1;
for i = 1:nIntervals
DAPrice(i,1) = e_Auktion24Energie(cnt,1);
if mod(i,4) == 0
cnt = cnt + 1;
end
end
DA_Price = repmat(DAPrice,1,4);
with the much simpler and more robust:
>> ucd = load('unitCommData.mat','T','loadProfile');
>> dap = load('DA_price.mat');
>> P = kron(dap.e_Auktion24Energie,ones(4))
P =
31.72 31.72 31.72 31.72
31.72 31.72 31.72 31.72
31.72 31.72 31.72 31.72
31.72 31.72 31.72 31.72
28.63 28.63 28.63 28.63
28.63 28.63 28.63 28.63
28.63 28.63 28.63 28.63
28.63 28.63 28.63 28.63
27.86 27.86 27.86 27.86
27.86 27.86 27.86 27.86
...
35.44 35.44 35.44 35.44
35.44 35.44 35.44 35.44
35.44 35.44 35.44 35.44
31.07 31.07 31.07 31.07
31.07 31.07 31.07 31.07
31.07 31.07 31.07 31.07
31.07 31.07 31.07 31.07
28.31 28.31 28.31 28.31
28.31 28.31 28.31 28.31
28.31 28.31 28.31 28.31
28.31 28.31 28.31 28.31
The second half of your code can be simply replaced with this line:
>> X = repmat((1:size(P,1)).',1,4)
X =
1 1 1 1
2 2 2 2
3 3 3 3
4 4 4 4
5 5 5 5
6 6 6 6
...
91 91 91 91
92 92 92 92
93 93 93 93
94 94 94 94
95 95 95 95
96 96 96 96
Which you can trivially access using indexing. So far there is no reason why you require lots of magically named variables.
