Non Linear Regression: Error: Symbolic parameters are expected. [stats::re​g::checkPa​rameters]

I want to find the ideality factor from the experimental data of a diode. I have obtained 10 I(sampleY) and V(sampleX) values, and used matlab `stats::reg` function to apply Univariate Nonlinear Regression.

I typed the following, however the matlab keeps on giving error message: `Error: Symbolic parameters are expected. [stats::reg::checkParameters]`.

    sampleX := [0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0]:
    sampleY := [0, 0, 0, 0, 0, 0, 0, 0.07, 0.92, 12.02, 158.29]:
    plot1 := plot::Scatterplot(x, y, LinesVisible = FALSE):
    plot(plot1)
    fit := stats::reg(sampleX, sampleY, ((10^-9)*(exp(38.68/n)-1)), [n], [0,0])

Can anyone please suggest any improvements for my code. I am using the mupad on matlab. I am new to this website and I am unsure whether this is the right place to ask this.

I think the problem is the [0,0] - I am unsure what I should input here.
