Hi, I am a beginner. I have three probs. 1) How to input the default angle in degrees rather than in radians?
2) I defined a as shown and calculated det(a)
The ans should be zero but the output is a value very close to zero. But I want a zero. How do I do that?
3) How do I learn MATLAB? Should I read some book or should I just go through the help section one article after another?
