Please, how do I write the equation in the picture in matlab? I have been getting errors. i used (.*) to multiply too.

for a= 1:1:90; b = 1:1:360. Cos_A OI = cos(a) x cos(as) x cos(b-As). + sinca) x sin(As). pm Please how do I write this in Matlab? The quantities are in degrees. for for a= b= 1:1:90; 1:1: 360. Cos_AOI = cos(a) x cos(as) * cos(b-As) + sinca) x sin(As) pin pm Please how do I write this in Matlab? the quantities are in degrees. As and as are data file uploaded There are more of them but I just uploaded a section that is actually giving me issues. I hope I get the rest I don't know how to upload the data here and even the whole matlab Code
