Where x and y are the vectors (Our signals) in question. We’re going to use command conv.Ĭommand conv is used to work with one-dimensional arrays and allows to handle the length of the result. Scilab provides several commands to perform convolution, nevertheless, each one has its own specialty, for example, convol uses Fast Fourier Transform, conv2 is used to work with two-dimensional arrays and frequently used in Image Processing. Also, it’s a basic topic in engineering study programs, therefore if you are immersed in the engineering world, this tutorial will be useful for you.Ĭonvolution operation of two discrete-time signals is defined as follow:įigure 2: Convolution of two continuous-time signals. ConvolutionĬonvolution is a mathematical operation whose applications are mostly in areas like Systems and Signal Processing, Physics and Engineering. I want you to learn the details about using the function conv in order to obtain very good results. Convolution mathematical operation knowledge.įinally, I decided to make a tutorial about Convolution, since is quite difficult to find examples and very good tutorials (even made in Matlab) about this mathematical operation.
