Farshid - try usingcellfun. It seems that thepnis a cell array with 38 elements and each element is a 8x1 char array. You haven't mentioned if each of the 8 characters is a single number or if all 8 combine to one (I'll assume the latter). ...
1 Matlab中图像数据类型转换：MATLAB中读入图像的数据类型是uint8，但在矩阵运算中的数据类型是double；因此I2 = im2double(I1) :把图像数组uint8 类型(I1)转换成double精度类型；如果不转换，在对uint8进行加减时会产生溢出，可能提示的错误为：Function '*' is not defined for values of class &#...
调用char 函数。如果字符向量的长度不同,char 将用尾随空格填充较短的向量,以使每 一行具有相同数量的字符。 mgrTitle = char('Harold A. Jorgensen', ... 'Assistant Project Manager', 'SFTware Corp.') mgrTitle = 3×25 char array 'Harold A. Jorgensen ' 'Assistant Project Manager' 'SFTware Corp....
str2doubleq is equivalent to the Matlab built-in str2double function that converts char or cellstr array to appropriate double arrays. The drawback of built-in str2double is that it becomes very slow when the dataset becomes larger. str2doubleq exploits C++ fast string handling capabilities. Also...
I used 'datenum' to convert date to number. And then used datestr to see the date and the result is as follows.<123x11 char> val = 01-Jan-1961 02-Jun-1965 ... How can I convert this character to double? 댓글 수: 0 댓...
5、表达式!注意,这里有一个小问题 ,就是 dec2bin 函数的返回值是一个 char array, 所以,我们应该先将 其转换为 double array! 可以利用 double() 进行强制类型转换 , 得到 ASCII 码值 , 减去 48 就可 以得到 double array 类型的 0,1 序列 !程序代码如下 : num,numint,numf=dectobin1(innum,N) %...
Matlab抛出的异常说明str2num函数使用错误,参数必须是字符数组(char array)或者是字符串(string)。在后台看了下获得的listbox里面的数据如下: list_string = ' 56 30 3.09 0' ' 32 46 3.83 30' ' 19 48 3.91 76' ……(省略一大堆数据) ' 31 301 9.79 6634' ...

Hello, I want to convert an array stored with binary values into a double value which has those binary values but in one number. For example, A=[1 0 0 1 0 1] to B=[100101]. What is the logic behind this? 댓글 수: 0 댓글을 달려면 로그인하십시오....
