The relationship y = a*x*eb*x, where a and b are unknown coefficients, is estimated to fit the following data set: x 0.1 0.2 0.4 0.6 0.9 1.3 1.5 1.7 1.8 y 0.75 1.25 1.45 1.25 0.85 0.55 0.35 0.28 0.18

Write a program using non-linear regression to estimate the values of a and b. This is an iterative process. You need to define the criterion for convergence, which is the tolerance between the values of a and b in two successive iterations. If the differences of both a and b in two successive iterations are less than this tolerance (say 10-4), the process has converged.
Check the number of iterations it takes to converge. Submit in a report the resulting values of a and b, the number of iterations the process takes to converge, and a plot showing the data and the fitted curve, to check visually the quality of the fit.

Please submit your program also. You may use functions from the numpy library to perform the required matrix operations, such as numpy.linalg.inv for inverting a matrix, numpy.linalg.matrix_transpose for transposing a matrix, numpy.linalg.matmul for matrix-matrix multiplication, and so forth.The relationship y = a*x*eb*x, where a and b are unknown coefficients, is estimated to fit the following data set: x 0.1 0.2 0.4 0.6 0.9 1.3 1.5 1.7 1.8 y 0.75 1.25 1.45 1.25 0.85 0.55 0.35 0.28 0.18

Hello all,
I hope you are all doing well. I have established a 2DOF differetial equation. Basically, the equations are the 2 spring-mass-damper system. But I am wondering how to define the variable X to be a dimentionless variable, such as X/L. In my equations, the variable X should be dimensionless but when I exclude the force (F_o the dimensionless force), the results of the equation are not dimensionless which I have already checked. My codes are attached. I think you can easily run it.
I appreciate your support.

Hi there,
My task is generating a list of all edges in mesh. (ps. I mean not edges of geometry, i saw some function there, which shows edges of a geometry, they are performed bases on interacting between mesh and geometry.)
For a mesh i can easily get access to elements (3d : tetraeder). I am considering break down each element into four faces. It’s easy for me to get edges from faces (2nd step).
(elements -> faces -> edges)
now the problem is in 1st step. A 3d quadratic case, that means an element consists of ten nodes. I have no idea which node is vertices which is in middle of edges.
The way to create mesh :
cubic = [100, 50, 20];
model = createpde(thermal="transient");
geo = multicuboid(cubic(1), cubic(2),…
cubic(3), ‘Zoffset’, 0);
model.Geometry = geo;
generateMesh(model, GeometricOrder=’quadratic’);
pdemesh(model)
Is there any tips for me?
Thank you all.

Best regards

Hello everyone,
I’m having problems with the heavy computational load of a Simulink model while running it in real-time. The profiler indicates that the model’s switches are consuming a significant amount of computation time. Does anyone have any recommendations for me, or have they encountered similar issues? If so, please assist me in resolving the issue.
I was wondering if somebody has any alternative model for a MOSFET (or a switch acts as a circuit breaker) that makes the simulations a bit less non-linear. That would be highly appreciated.
