Wind power is extracted from air flow using wind turbines or sails to produce mechanical or electrical power. Windmills are used for their mechanical power, windpumps for water pumping, and sails to propel ships.ind farms consist of many individual wind turbines which are connected to the electric power transmission network. Onshore wind is an inexpensive source of electricity, competitive with or in many places cheaper than coal or gas plants.
Defining a matrix in Matlab is similar to defining a vector in Matlab. To define a matrix, treat it as a column of row vectors. Note that spaces between number is used to define the elements of matrix and semi-colon is used to separate the rows of matrix A. The square brackets are used to construct matrices.
Introduction. MATLAB Â® has two different types of arithmetic operations: array operations and matrix operations. You can use these arithmetic operations to perform numeric computations, for example, adding two numbers, raising the elements of an array to a given power, or multiplying two matrices.owever, since the matrix and array operations are the same for addition and subtraction, the character pairs .+ and .- are unnecessary.
