Is there a wait command in MATLAB?

How do you delay in MATLAB?


  1. When delay is a scalar, the function applies the same delay to each column of data .
  2. When delay is a vector: If data is a matrix, the length of the delay vector must equal the number of columns in the matrix. The function applies a delay to each column using the corresponding delay entry.

How do I wait for user input in MATLAB?

x = input( prompt ) displays the text in prompt and waits for the user to input a value and press the Return key. The user can enter expressions, like pi/4 or rand(3) , and can use variables in the workspace. If the user presses the Return key without entering anything, then input returns an empty matrix.

What is delayed signal?

Signal delay is defined as that delay which maximizes the correlation between input signal and output signal of a system. Its derivation requires splitting of the delay into the additive components linearity delay and inter- cept delay.

How do you show results in Matlab?

To display the result in the command window without displaying ans , use the disp function. If an expression is terminated by a semicolon, MATLAB does not display a value, but still assigns the result to the ans variable.
