Any non-zero number is considered to be logically true. xor() of true and something else is going to the logical NOT of the second value -- so it is going to be 0 if the second value is non-zero, and is going to be 1 Thank...
example: I have a vector A=[1;5;7;4]; I want it to be S= [ テーマコピー 1 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 1 0 0 0 1 0 0 0]; Is it possible to do this without for loop? Thanks 0 件のコメント ...
1. uint8 与 double Images don’t show with imshow after converting them to double. 另外对于 uint8,相加、相乘,都容易溢出,所谓溢出,就是得到的超过 255 的结果,都会截断为 255,一般这种情况,即会出现相加相乘运算时,先转换为 double 类型。 matlab 对数值类型十分敏感, 对uint8 类型,期待其值域范围为 ...
char:Convert to character array,转换为字符数组;matlab 下没有 str 字符串类型转换; char(0-255) ⇒ ASCII 码的转换; im2double(): 将intensity image (0-255,uint8 的整型类型)转换为 0-1 的 double 类型(double precision,双精度); 0. ismatrix() ismatrix 对于三维的矩阵返回值为 logical false。...
2、uble - Convert to double precision. char - Create character array (string). logical - Convert numeric values to logical. cell - Create cell array. struct - Create or convert to structure array. single - Convert to single precision. uint8 - Convert to unsigned 8-bit integer. uint16 -...

1×0 empty double row vector ans = 1×0 empty double row vector ans = 1×0 empty double row vector ans = 2 Even with this quick test which took only a few seconds to run on my computer, we see that 3 of those Mersenne numbers are clearly not prime. In fact, we already know th...
1. ANSI C requires an integer cast of a double argument to correctly use an integer conversion specifier like d. A similiar conversion is required when using such a specifier with non-integral MATLAB values. Use FIX, FLOOR, CEIL or ROUND on a double argument to explicitly convert non-integra...
So, is there a correct way to convert a double into a vpa? I have many other places in the code where I do similar conversion from double to vpa. If they are all similarly random digits after the 14th decimal position, I'm in big trouble... Cheers...
I need to convert my matrix [648x2400 double] into integers value to use a mRMR function, but I do not know how to do that. I have tried to convert by uint8(matrix) or int8(matrix) but it does not give integers... And I always have this note: "Undefined function 'mrmr_mid_d...
