For the modeling of PV array, we used MATLAB Simulink. Write code to run the model from the m-file using the “sim” command. Description. Each input vector is saved in a row of the output matrix, vertically concatenated onto the previous vector. Programmatic Use. For numeric input data, you can also specify the format of display. , a vector), the resulting workspace array is two-dimensional. For array inputs, the output is an array of the same dimensions, where each element is the result of an element-by-element comparison of the input arrays. You can create common arrays and grids, combine existing arrays, manipulate an array's shape and content, and use indexing to access array elements. I made him a few examples that I am sharing today in this post. If the input signal is an unoriented vector, the resulting workspace array is 2-D.
