How do you do logistic regression on with this data? I am having trouble finding a correct model as I am relatively new to Matlab and programming.

What are your predictor and response variables?

I'm working on doing a logistic regression using MATLAB for a simple classification problem. I have 9 continuous variables ranging between 0 and 1, while my categorical response is a binary variable of 0 (incorrect) or 1 (correct).
I'm looking to run a logistic regression to establish a predictor that would output the probability of some input observation (e.g. the continuous variable as described above) being correct or incorrect.

You don't give us much detail, so we can't give you a detailed answer.
If you have the Statistics and Machine Learning Toolbox, there is a good chance that you can use the fitglm function to do the regression. That documentation link has examples.

A classifier might be a more appropriate approach than a regression. My first choice would be the classify function to do a discriminant analysis.
