CWTFTINFO2信息小波对CWTFT2 CWTFTINFO2提供信息可用小波二维连续小波变换使用FFT。小波是由傅里叶变换。公式给小波的傅里叶变换的短名称(见下文)使用CWTFTINFO2 SNAME将显示(SNAME)。下表提供了每个小波的短名称和相关的参数:首先,参数的名称,然后默认值。WAV_Param_Table = {…morlet,违约:ω= 6;σ= 1;ε= 1;马尔,违约:p = 2;sigmax = 1; sigmay = 1; 'paul' , defaults: p = 4; 'dog' , defaults: alpha = 2; 'cauchy' , defaults: alpha = pi/6; sigma = 1; L = 4; M = 4; 'escauchy' , defaults: alpha = pi/6; sigma = 1; L = 4; M = 4; 'gaus' , defaults: p = 1; sigmax = 1; sigmay = 1; 'wheel' , defaults: sigma = 2; 'fan' , defaults: omega0 = 5.336; sigma = 1; epsilon = 1; J = 6.5; 'pethat' , defaults: No parameters.
