It is my understanding that you are trying implement static contexts instead of always passing them across the interface. And perform embedded use of Excel from the compiled Python Library.
You can define a variable as persistent to give "static-like" behaviour in a MATLAB function, but its scope is limited within that function.
Here, in the following implementation (say, ‘StateManager.m’), I have used persistent variable, and appended its value to an excel file using “tablewrite”.
function result = StateManager(val)
persistent ctx;
if isempty(ctx)
ctx = 0;
end
ctx = ctx + val;
result = ctx;
% append to excel file
filename = 'state.xlsx';
if ~exist(filename, 'file')
writetable(table(ctx), filename);
else
writetable(table(ctx), filename, WriteMode='append');
end
end
When the function is called repeatatively, the previous values are retained in memory between calls.
newVal = randi(100);
ctx = StateManager(newVal);
fprintf('State: %d, new-val: %d\n', ctx, newVal);
newVal = randi(100);
ctx = StateManager(newVal);
fprintf('State: %d, new-val: %d\n', ctx, newVal);
