Convolution is a mathematical operation that combines two functions to describe the overlap between them. Convolution takes two functions and “slides” one of them over the other, multiplying the function values at each point where they overlap, and adding up the products to create a new function...
Znoise = Z + rand(100) - 0.5; contour(Znoise,levels) Theconv2function in MATLAB® convolves 2-D data with a specified kernel whose elements define how to remove or enhance features of the original data. Kernels do not have to be the same size as the input data. Small-sized kernels...

MATLAB Online で開く This is hopefully a problem that the symbolic toolbox's 'int' function could solve for you. The convolution of the two functions you have given can be expressed as: F(t) = int(f(s)*h(t-s),'s',-inf,+inf) ...
and it is widely used in block filtering techniques. Manually finding the convolution of two vectors or polynomials is a complicated operation; however, in the era of high-performance computing tools like MATLAB, it has become an easy task to calculate convolution using theconv()function. ...

When looking at the CPU utilization, I noticed that the ND convolution function (convn) does not use multiple cores when operating on greater than 2D arrays. A=randn(500,500); B=randn(500,500); C=convn(A,B,'same');% all 12 CPUs are utilizedA=randn(500,50,10); ...
I have a curve (let's assume it's a continuous function) that fluctuates in x,y space wtih regions of monotonically increasing and decreasing data. Each y-value will have a probability density value. I would like to transform the dataset, so that the y-data becomes the "new" x-value...
