I want to do OCR, but sometimes I get the letters with a specific inclination, I can detect the angle, but I am not sure how to contruct the transformation matrix.

hmm, look at this

(imho, you got shearing there, not a plain rotation. this is no more an affine transform)

(if you rotate it, e.g, the 't-crosses' won't be horizontal any more)

I still do not get the formula for the value in the perspective matrix... Can you suggest me something?

Can you add some sample images? If it is a planar warp, you can find the homography and correct the warping.
