Rotate nxn matrix around x-axis by an angle theta in Matlab

I have nxn matrix in 2D space; I would like to rotate the matrix around the x-axis using matlab. Where the x-axis pass through the center of the matrix (pass through the point [n/2 n/2].

I found the Matlab function B = rot90(A) which rotate the matrix A by 90 degree. But I’m looking for a method that rotate matrix A by any given angle (e.g. 30, 45, 170 degree) around the x-axis.

You can as well try imrotate(). This function is from the Image Processing Toolbox, but since its main input is a matrix (either real or logical) it'll work also for non picture-related matrices (I've tried with a magic matrix).

The syntax is:

B=imrotate(A,theta);

where A is you matrix, B is the rotated version of A and theta is the rotation in degrees. The rotation is performed in counterclockwise direction around its center point; to rotate the matrix clockwise, specify a negative value for theta.
