如果 A 属于 logical 数据类型,则 imwrite 会假定数据为二值图像并将数据写入位深为 1 的文件(如果格式允许)。BMP、PNG 或 TIFF 格式以输入数组形式接受二值图像。如果 A 包含索引图像数据,则应另外指定 map 输入参数。 imwrite(A,map,filename) 将 A 中的索引图像及其关联的颜色图写入由 map filename 指定...
tf =logical1 Representation of numeric matrix |string scalar Representation of a numeric matrix, specified as a character array or string scalar. Text that represents a numeric matrix can contain spaces, commas, or semicolons, such as'5','10,11,12', or'5,10;15,20'. In addition to nume...

对于向量,应使用&和|操作符。双写的(&&和||)称为Short-Circuit Operators,其特点是,如果逻辑运算的结果可以由第一个操作数确定,则不计算第二个操作数,但只适用于标量;单写的(&和|)称为Element-wise Operators,可以于操作数是数组的场合,运算按照数组对应位置的元素进行与/或操作。对于这样...
