(Original issue) How can I solve the problem of saving enough attention in MATLAB after removing the DSP Builder? (SOC) (DSP Builder) (MatLab)

Abstract
If the DSP Builder is installed in MATLAB, after the DSP Builder is removed in a day, as long as the MATLAB is moved together, there will be negative information. How can this problem be solved?

Introduction
Environment: MATLAB r200b

Previously, I installed DSP Builder 7.2 and 8.0, but after Quartus II 8.1, I didn't install DSP Builder again, and I found that using Matlab, the following response message is displayed:

The solution is as follows:
Step 1:
Use NotePad to Open c: \ Program Files \ MATLAB \ r2007b \ toolbox \ Local \ pathdef. m, and delete all links related to Quartus II.

Step 2:
Re-activate MATLAB and there will be no additional warning information.
