Matlab matrix file format

If the matrix contains real numbers, then there is one number, which is the value of the matrix entry. If the matrix contains complex numbers, then there are two numbers, which are the real and complex components respectively of the matrix entry's value. In either case, each component is read in as a double-precision floating-point value, even if the actual precision is less or more.

We use the C standard library routine strtod to do this, so the way the routine rounds extra digits depends on the C standard and your system's implementation of strtod.

Print Double-Precision Values as Integers. Write Tabular Data to Text File. Get Number of Bytes Written to File. Display Hyperlinks in Command Window.

Input Arguments collapse all fileID — File identifier 1 default 2 scalar. File identifier, specified as one of the following: A file identifier obtained from fopen. Identifier Order for processing the function input arguments. Flags '—' Left-justify. Note If you specify a precision operator for floating-point values that exceeds the precision of the input numeric data type, the results might not match the input values to the precision you specified.

Ordinary text to print. Numeric conversions print only the real component of complex numbers. Numeric or character arrays, specified as a scalar, vector, matrix, or multidimensional array.

Output Arguments collapse all nbytes — Number of bytes scalar. Tips Format specifiers for the reading functions sscanf and fscanf differ from the formats for the writing functions sprintf and fprintf. References [1] Kernighan, B.

Usage notes and limitations: The formatSpec parameter must be constant. Extrinsic calls are disabled. You have a modified version of this example. Do you want to open this example with your edits? No, overwrite the modified version Yes.

In fact, you made your first array by concatenating its individual elements. The pair of square brackets [] is the concatenation operator. Concatenating arrays next to one another using commas is called horizontal concatenation.

Each array must have the same number of rows. Similarly, when the arrays have the same number of columns, you can concatenate vertically using semicolons. Complex numbers have both real and imaginary parts, where the imaginary unit is the square root of To represent the imaginary part of complex numbers, use either i or j.
