No credit if you you just type in the values. Make a similar output using disp( ) and num2str( ) functions with a single disp() function. No credit if you you just type in the values.Ĥ. You need to use 2 proper %f format strings. Hint: a number like 1.34 needs 4 characters, so use %4.2f Where x.xx and y.yy will be replaced with your values. Display the mean and standard deviation values to the screen using fprint( ) with a %f format code (with 2 decimal places) to create a string like: Compute the mean and standard deviation of the vector.ģ. X = randi(6,1,36) % Create a vector with uniform random integers between 0 and 6.Ģ. Read this ASCII file back into a two-column MATLAB matrix:Ī = fscanf(fid,'%g %g' ,) % It has two rows now.\) Mimic dice rolls The example in fprintf generates an ASCII text file called exp.txt that looks like: Mixing character and numeric conversion specifications cause the resulting matrix to be numeric and any characters read to appear as their ASCII values, one character per MATLAB matrix element.įor more information about format strings, refer to the scanf() and fscanf() routines in a C language reference manual. Use %c to read space characters or %s to skip all white space. If %s is used, an element read may use several MATLAB matrix elements, each holding one character. Sequence of characters number specified by field width The size of the receiving object for example, h for short as in %hd for a short integer, or l for long as in %ld for a long integer or %lg for a double floating-point number. If %*d, then the value that matches d is ignored and does not get stored. Conversion specifications indicate the type of data to be matched and involve the character %, optional width fields, and c onversion characters, organized as shown below:Īdd one or more of these characters between the % and the conversion character: The format string consists of ordinary characters and/or conversion specifications. If a partial match occurs, only the matching data is written to the matrix, and the read operation stops. If a match occurs, the data is written into the matrix in column order. When MATLAB reads a specified file, it attempts to match the data in the file to the format string. The format string is cycled through the file until an end-of-file is reached or the amount of data specified by size is read in. n can be Inf, but not m.įscanf differs from its C language namesakes scanf() and fscanf () in an important respect - it is vectorized in order to return a matrix argument. Read enough elements to fill an m-by- n matrix, filling the matrix in column order. Read to the end of the file, resulting in a column vector containing the same number of elements as are in the file. size is an argument that determines how much data is read. Reads the amount of data specified by size, converts it according to the specified format string, and returns it along with a count of elements successfully read. format is a string specifying the format of the data to be read. Argument fid is an integer file identifier obtained from fopen. Reads all the data from the file specified by fid, converts it according to the specified format string, and returns it in matrix A.
