How can I get slope from DEM data?

Hi, I'm undergraduate student from Yonsei University, Seoul. I have a question about MATLAB.
I have a DEM data like this picture.
Each row and column indicates the length of data set(1952X2101), and each value means elevation.
I want to calculate the slope of radom radial degree.
If I put random radial degree like 45 degree(0-90 degree), MATLAB shows slope like 0.08 (in ratio)
How can I make this one?
Thanks for reading.
