Need to get an input to a curve fit toolbox application in datetime format

Hi, I need an input to a curvefit routine using a datetime input. The toolbox won't recognize the datetime array I created as the x-axis input. Can I convert this datetime array to a simple number array that it will recognize? How? Thanks.

Did you use 'datenum' function?

Try to use 'datenum' function to convert 'datetime' and then use the curve fitting toolbox function on 'datenum' object.
