Sometimes MATLAB users need to scale the y-axis as a log scale keeping the x-axis as a linear scale while plotting a function or an expression. This can be obtained easily by using thesemilogy()function. Thesemilogy()function allows us to create two-dimensional plots of a function or expr...

Machine learning and data mining algorithms use techniques from statistics, optimization, and computer science to create automated systems which can sift through large volumes of data at high speed to make predictions or decisions without human intervention. Machine learning as a field is now ...
