Rules for variable names:
In addition, the variable names must always be mnemonic that means they should make some sense. For illustration, if the variable is storing the radius of a circle, a name like "radius" would make sense; "x" perhaps wouldn't.
The Workspace Window represents the variables which have been created in the present Command Window and their values.
The commands shown below associate to variables:
(i) Who shows variables which have been defined in this Command Window (this merely represents the names of the variables)
(ii) Who shows variables which have been defined in this Command Window (this represents more information on the variables, likewise to what is in the Workspace Window)
(iii) Clear clears out all the variables, therefore they no longer exists.
(iv) Clear variablename clears out a specific variable.
Expand a matrix: To expand a matrix, an individual element could not be added as that would mean there would no longer be the similar number of values in every row. Though,
i want to extract an image from its background in matlab..the image is a binary image

Generates sin or cos wave using plot functions: The script generates an x vector; iterating through all the values from 0 to 2*π in steps of 2*π /40 gives sufficient points to
1. Enter the 3×4 matrix Let a ij denote the entry of A in the ith row and jth column. Use Matlab to compute the following : (a) a 13 + a 32 (b) Three times the
Example of variable names: If nothing appears when, who or whose is entered, which means there aren't any variables! For illustration, in the starting of a MATLAB session, the
A filter described by the equation: y(n) = x(n) + x(n-1) + 0.9 y(n-1) - 0.81 y(n-2) (a) Find the transfer function H(z) for the filter and find the poles and zeros of the fil
why we use wavelet in image processing ?
Size function - Dimensions of matrix: For the matrix mat shown next, it has three rows and two columns, therefore the size is 3 × 2. The length is the larger dimension that is
An FIR filter has coefficients b = [ 1.0000 -0.6387 1.0214 0.8210 -0.7470 1.0920 ] (a) Find H(z) for the filter and plot its frequency response (magnitude and phase
