I'm getting this error when I'm trying to do a regression analysis with the function 'model_output = fitlim'. I read somewhere online that it may be due to too many variables (it's a lot in the thousands) but shouldn't Matlab be able to handle it? I'm very new to Matlab just this week so don't have a lot of experience with the software.
I tried to only using about 30 variables and then the function worked but I absolutely need to be able to do with all of my variables. The variables originate from Excel sheets which I only have done log function on beforehand.

As Jan alludes to, the problem here is likely not Matlab but the underlying data. How many variables versus how many observations do you have? Does that tell you something?

Is it necessary to normalize all the design variables between 0 and 1 before trying to use fitglm?
