WebC = setdiff(A,B, ___,'rows') and C = setdiff(A,B,'rows', ___) treat each row of A and each row of B as single entities and return the rows from A that are not in B, with no repetitions.You must specify A and B and optionally can specify setOrder.. The 'rows' option does not support cell arrays, unless one of the inputs is either a categorical array or a … Webdiff (函数,变量名,n),求对的n阶偏导数;. 数值微分函数也是用diff,因此这个函数是靠输入的引数决定是以数值或是符号微分,如果引数为向量则执行数值微分,如果引数为符号表示式则执行符号微分。. diff函数用以演算一函数的微分项,相关的函数语法有 ...
