s = num2str(A) converts a numeric array into a character array that represents the numbers. The output format depends on the magnitudes of the original values. num2str is useful for labeling and titling plots with numeric values. example. s = num2str(A,precision) returns a character array that represents the numbers with the maximum number of ...
s = num2str(A) 将数值数组转换为表示数字的字符数组。. 输出格式取决于原始值的量级。. num2str 对使用数值为绘图添加标签和标题非常有用。. s = num2str(A,precision) 返回表示数字的字符数组，最大有效位数由 precision 指定。. s = num2str(A,formatSpec) 将 formatSpec 指定的格式 ...
Description. s = num2str(A) converts fi object A into a character array representation. The output is suitable for input to the eval function such that eval(s) produces the original fi object exactly. s = num2str(A,precision) converts fi object A to a character array representation using the number of digits of precision specified by precision.
Here are three ways to display multiple variable values on the same line in the Command Window. Concatenate multiple character vectors together using the [] operator. Convert any numeric values to characters using the num2str function. Use disp to display the result. X = [name, ' will be ',num2str(age), ' this year.'];
Please use the following command: >> num = 47; >> num2str (num,'%03.f'); The '%03.f' format specifier indicates that there would totally 3 digits before the decimal point prepended with 0 depending on the digits in the number.
This operator automatically converts numeric values to strings when the other operands are strings. For example, plot a sine wave. Calculate the frequency of the wave and add a string representing that value in the title of the plot. X = linspace(0,2*pi); Y = sin(X); plot(X,Y) freq = 1/(2*pi); str = "Sine Wave, Frequency = " + freq + " Hz".
Formatting Text. To convert data to text and control its format, you can use formatting operators with common conversion functions, such as num2str and sprintf. These operators control notation, alignment, significant digits, and so on. They are similar to those used by the printf function in the C programming language.
Description. X = str2num(txt) converts a character array or string scalar to a numeric matrix. The input can include spaces, commas, and semicolons to indicate separate elements. If str2num cannot parse the input as numeric values, then it returns an empty matrix. The str2num function does not convert cell arrays or nonscalar string arrays, and ...
how could I write a string like the following word+number+word with number=num2str(x). For example:
If uninitiated in the secrets of (Matlab's) regular expressions: \s stands for any whitespace and the + means 1 or more times. This is needed because the amount of space between the numbers output by num2str varies depending on the length of those numbers.
