Y = acosd( X ) returns the inverse cosine (cos–1) of the elements of X in degrees. The function accepts both real and complex inputs. For real values of X in the interval [-1, 1], acosd(X) returns values in the interval [0, 180].
How do you do natural log in MATLAB?
Y = log( X ) returns the natural logarithm ln(x) of each element in array X . If you want negative and complex numbers to return error messages rather than return complex results, use reallog instead.
How do you do log in MATLAB?
Y = log10( X ) returns the common logarithm of each element in array X . The function accepts both real and complex inputs. For real values of X in the interval (0, Inf ), log10 returns real values in the interval ( -Inf , Inf ). For complex and negative real values of X , the log10 function returns complex values.
How do you make a dot product in MATLAB?
- If A and B are vectors, then they must have the same length.
- If A and B are matrices or multidimensional arrays, then they must have the same size. In this case, the dot function treats A and B as collections of vectors.
How do you print in MATLAB?
- Type the name of a variable without a trailing semi-colon.
- Use the “disp” function.
- Use the “fprintf” function, which accepts a C printf-style formatting string.
