Recently in handover task, use to matlab,mark a novice knowledge point.
The way to learn is to see not just foridom under or 91, so the information is trivial. But it's still in my head (*^__^*) ...
Tic......toc% can calculate time;
- The H = fspecial (Type,para)% function is used to establish a pre-defined filter operator;
- For example fspecial ("Gaussian", 19,1.5)% means using Gaussian filtering, window for [19*19],sigma=1.5
- strcat (' xx ', num2str (i)); % for connection strings, num2str for type conversions;
- End% exists in For,while,switch, try,if,parfor statements;
- [Y,settings]=mapminmax (X,varargin)% maps x to the [ -1,1] interval;
- Zeros ()% generates a full 0 matrix,
- Ones ()% generates all 1 matrices;
- For i = 1:5 is equivalent to for i = 1:1 5 is the step length of 1 is not written;
- Filter2 ()% two-dimensional filter;
