The fprintf documentation give two syntaxes for specifying any unicode character directly: The symbolic expression has to be first converted into a character array (string) using the CHAR function. Right now it is only printing out only this This is most likely the cause of the strange characters you are reporting. The printable display of symbolic functions and symbolic expressions is intended for human understanding, not for machine execution. Improve this question. When you change the values of a and/or b you need to update all relevant variables that depend on those values, so not only c, which you have done, but also prod_ac and prod_bc, because if you don't update those, the code inside the while loop uses the old values which were based on the old a, b and c. Surely, there must be a way to print the same expression to a file. 1 Matlab cho kết quả 2^(1/2) nghĩa là 21/2, bằng cách sử dụng ký hiệu symbolic cho phép toán căn bậc hai, mà không tính After saving it in a . .

I want to use fprintf to print my matrix 2x2 like a normal matrix and not on a single line like I have with this command : fprintf('%s', Lplanoconvexe. char() of a symbolic expression is really only suitable for entering the expression back in to the symbolic toolbox. Here's an example: syms x y z; %# Specify your symbolic inputs to fprintf with %s placeholders and use char to convert them to characters. disp(['Line 1' newline 'Line 2']) You mention using fprintf, but as you found this is meant for writing to files. fprintf() and sprintf() have exactly the same The numeric part is solved by it, but displaying the symbolic equation with fprintf is not. I am having a lot of trouble trying to make symbolic substitution go faster - that is, substituting in for variables in a symbolic expression and getting out a double. Both a and b are equal to 3, but that doesn't mean a is b. For example, f(x,y) = x + y. The return value from fprintf() is the number of characters printed, not the string. displayFormula(symstr) displays the symbolic formula from the string symstr without evaluating the operations. I am new user of matlab. I use it in plots and it works. However, Matlab gives me an answer with real & imaginary parts. I tried: C=60; eq= sprintf('\epsilon = %d x^2',C); text(x,y,eq) but that doesn't work. Note that in this instance, the results of FPRINTF MATLAB matches all characters in the name exactly except for the wildcard character *, which can match any one or more characters.

This will symbolically substitute variables in your symbolic matrix with another expression. xxxx x^2 . You either need to pre-process the text before it's printed to file or post-process the file to apply backspaces and rewrite. So, if my X = 25, and I need it to display 25 ft/lb, how would I do this? Note: char() of a symbolic expression does not generally result in a string that can be evaluated by MATLAB. The same is true for the code: a = 3; b = a; b This gives b = 3, not b = a.

For In Matlab 2016a, Mathworks deprecated the use of the sym function for parsing symbolic expressions: >> expr = sym('x + 1') Warning: Support of strings that are not valid variable names or define a number will be removed in a future release. f you use it if you want the number to be indented by 4 whitespaces and take just the integer part. Sometimes they look like MATLAB code, but they contain parts that are not MATLAB, and some of the functions have a different parameter order than MATLAB uses. Note that pattern matching means matching expressions in this context, not strings. fprintf Matlab® provides many methods to output data, of which Table 1 shows the most used. For the complete set of rules MATLAB applies for choosing a MATLAB is not designed to be able to tell the difference between 3/4 and 6/8: it will calculate the binary equivalents of the result and use that binary result, except in the Symbolic Toolbox where it will reduce the fraction to lowest In MATLAB I'm printing a very large matrix this way: fid = fopen('c:\\OUTPUT.
