hi, I have to develop a search in lookup table, the following task has to be performed. suppose assume the following lookup table as an example.
deg sine_value cosine_value; 0 0 1; 30 0.5 0.866; 45 0.707 0.707; 60 0.866 0.5 ; 90 1 0;
with the above lookup table as reference, i need to locate a sine_value first, and then i need to search for cosine value which matches with the row of sine_value. After both the values are retrieved then, the corresponding angle should able to retrieved in the angle column.
for example: first a search is made to find a value 0.5 in sine_value column, then a search is made to find a value 0.866 in cosine_value column. if both lies in same row then, the corresponding value in the angle column is retrieved... can u please help me how to develop this logic in mat lab( using simple mat lab commands).
