Hi everyone,

I've fitted some data to an nonlinear equation. The origin says it converged and shows me the parameters and the predicted valuens, all in accordance with the experimental data. The problem is, when I try to use these parameters on MatLab to plot the curve. The values can't be as far as they are from the original dataset. I'd already checked the equation both in origin and in matlab and it's all correct. Can someone please help me understand what may be happening?

Thanks in advance,

PS.: I'm using origin 2022b.

Could it be you didn't copy the full precision of the parameter values to MatLab? Please provide more information or better post a screenshot to show the issue. Thanks.

James
