The book begins assuming the reader has no previous programming experience, and it uses multiple examples and clear language to introduce concepts and practical tools. The straight-forward and detailed instructions provide quick and thorough learning of Matlab for the beginner, allowing them to improve quickly in a short time. The book consists of ten parts and it discusses in detail the integrated development environment (IDE), scalars, vectors, arrays, adopting structured programming style ...
