Hello,
I have 2 columns in Excel that I would need to calculate in Matlab. In the first column I have a formula: =IF(J2=1;IF(ISNUMBER(K1);K1+1;1);0) In the second column: =IF(AND(J2=1;J3<>1);K2;0) After column J, I have it calculated in matlab. Thank you very much for the advice.
I created column J in matlab with the command: T.Platoon=double(T.CasRozdiel<=4). I have added a matlab file in the attachment.
How it looks in excel.

I'm not sure what you want. Why not simply read your existing Excel workbook in to MATLAB with readtable? The computed values (the numbers), not the formulas, are what should be read in. And since you did the computations in Excel, then numbers should be right.

I understood that you want to calculate the values of two other columns based on some conditions in MATLAB.
You can try the following code
This code will iterate over each cell value of platoon and calculate the platoonTemp based on condition “if(J2=1;If(isnumber(K1);K1+1;1);0)” and similarly platoonTemp2 is calculated from values of platoonTemp based on condition “if(and(J2=1;J3<>1);K2;0)”.
n = size(T,1)
platoonTemp = zeros(n,1);
platoonTemp2 = zeros(n,1);
for i = 1:n
if T.Platoon(i)==1
if i~=1
platoonTemp(i)=platoonTemp(i-1)+1;
else
platoonTemp(i)=1;
end
end
if i~=n && T.Platoon(i)==1 && T.Platoon(i+1)~=1
platoonTemp2(i)=platoonTemp(i)
end
end
T.Temp1 = platoonTemp
T.Temp2 = platoonTemp2
I hope it answered your query
