CWTFTINFO2 CWTFT2 CWTFTINFO2的小波信息信息提供了有关使用FFT的2-D连续小波变换的可用小波的信息。小波由傅立叶变换定义。提供短名称（见下文）的小波傅立叶变换的公式将使用CWTFTINFO2（SNAME）来显示SNAME。下表给出了每个小波和关联参数的短名称：首先，参数名称，然后是默认值。wav_param_table = {...'morl'，默认值：omega0 = 6;Sigma = 1;epsilon = 1;'mexh'，默认值：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.
