Remember that lasso regression is a machine learning method, so your choice of additional predictors does not necessarily need to depend on a research hypothesis or theory Matlab Hello I would like to plot seismic data with a y range from 10 -7 to 10-1 (m*s) and an x range from 1 to 10 000 (Hz) on a log log plot. Since HEVC 2D IDCT performs matrix multiplication operations, it is suitable for HLS implementation CODE Complexity: HIGH Users capable of writing this This is the code i have at the moment I have been able to use These scripts should be in the directory folder where you are using Matlab. The MATLAB M-file used to create this plot is experr.m. To create a plot with a linear scale on the x-axis and a log (base 10) scale on the x-axis you can use the function semilogx. To create a plot using a log (base 10) scale for both the x-axis and and the y-axis you can use the function loglog. If Log10 [10^x] gives a line in a LogLog plot, then using it as Linear fit should work. Example: Thanks for contributing an answer to Mathematica Stack Exchange!
