Writing variables to a File:
The save command is used to write variables to a file, or to append the variables to a MAT-file. By the default, save function writes to a MAT-file. It can either save the whole present workspace (all variables which have been generated), or a subset of the workspace (involving, for illustration, just 1 variable). The function save will save the file in the present directory, therefore it is important to set that properly first.
To save all the workspace variables in a file, the command is as shown below:
save filename
The .mat extension is automatically added to the filename. The contents of the file can be exhibited by using who with the -file qualifier:
who -file filename
Use of string variables: The Characters involve letters of the alphabet, punctuation marks, digits, white space, and control characters. The Control characters are characters
Logical Vectors: The relational operators can also be used with the vectors and matrices. For illustration, let's say that there is a vector, and we want to compare each eleme
strvcat function - concatenation: The function strvcat will concatenate it vertically, that means that it will generate a column vector of the strings. >> strvcat(fir
how can reconstruct just part of an image using imreconstruct?
User-defined functions: Therefore, although many functions compute and return values, some do not. A few functions rather merely accomplish a task. Regardless of what type of
Illustration of Empty vectors: The Empty vectors can also be used to delete elements from the arrays. For illustration, to remove the third element from array, an empty vector
Illustration of Variance For illustration, for the vector [4, 6, 1, 5], there are n = 4 values therefore n - 1 is 3. The mean of this data set is also 4. The variance will be
Referring to and Modifying the Matrix Elements: To refer to matrix elements, the row and then the column indices are given in parentheses (always the row index initially and t
Polar Form: Any complex number z = a + bi can be thought of as a point (a,b) or vector in the complex plane in which the horizontal axis is the real part of z, and the vertica
Functions to create special matrices: The MATLAB also has various functions which create special matrices. For illustration, the zeros function generates a matrix of all zeros
