HELLO,

I am xTrain as cell array with [1 , 8614] and yTrain also Cell array[ 1, 4612]

Converting these to arrays with

X_poly = cell2mat(xTrain);

y_poly = cell2mat(yTrain);

passing these parameters to polyfit function

[X_polynominal, mu, info]=polyfit(X_poly,y_poly,p);

Getting an error of

X and Y vectors must be the same size.

please help in how to resolve these issue or my question is we cannot pass the different dimesnion of X and Y to polyfit?

Thanks for the answers

hi ,

thanks for the immediate reply

actually am using Xtrain

like this

xTrain = con2seq([...

(3v3Red(idxStart:end)');

(Bldc1_I1(idxStart:end)');

(Bldc1_I2(idxStart:end)');

(Data_0__Speed(idxStart:end)');

]);

yTrain = con2seq([...

Oil_Flow(idxStart:end)')

]);

and p = 2;

then , is there any other way we can pass these different arrays

Thank you

Check the dimensions of x, y ..they should be equal.
