How to force Matlab to be consistent with trigonometric expressions

2 views (last 30 days)
I have two symbolic matrices. They are identical, but the simplifications of their trigonometric expressions are not. Therefore, the appearance of the outcome is not similar in latex format. Matlab shortens one matrix for some reason but leaves extended expressions for the other. The following script illustrates this problem. The simplify() is not providing a consistent outcome. I've checked the equality of the two matrices by using isAlways() and numerical substitutions. I'm not sure if my question is a tall order, but how can Matlab be consistent with the outcome?
