  2. pandas (software) - Wikipedia

    en.wikipedia.org/wiki/Pandas_(software)

    However, if data is a DataFrame, then data['a'] returns all values in the column(s) named a. To avoid this ambiguity, Pandas supports the syntax data.loc['a'] as an alternative way to filter using the index. Pandas also supports the syntax data.iloc[n], which always takes an integer n and returns the nth value, counting from 0. This allows a ...

    In this, is the transfer function of the block . It works on the entry state i n b {\displaystyle in_{b}} , yielding the exit state o u t b {\displaystyle out_{b}} . The join operation j o i n {\displaystyle join} combines the exit states of the predecessors p ∈ p r e d b {\displaystyle p\in pred_{b}} of b {\displaystyle b} , yielding the ...

  4. Closed-loop transfer function - Wikipedia

    en.wikipedia.org/wiki/Closed-loop_transfer_function

    The closed-loop transfer function is measured at the output. The output signal can be calculated from the closed-loop transfer function and the input signal. Signals may be waveforms, images, or other types of data streams. An example of a closed-loop block diagram, from which a transfer function may be computed, is shown below:

  5. Transfer function - Wikipedia

    en.wikipedia.org/wiki/Transfer_function

    The transfer function of a two-port electronic circuit, such as an amplifier, might be a two-dimensional graph of the scalar voltage at the output as a function of the scalar voltage applied to the input; the transfer function of an electromechanical actuator might be the mechanical displacement of the movable arm as a function of electric ...

    en.wikipedia.org/wiki/Help:Advanced_table_formatting

    There are several advanced table formatting techniques to improve the display or editing of wikitables in Wikipedia. Most of the tips involve use of standard text-editors. While some special software packages exist, to allow customized editing, they are typically not available when travelling to other computers for wiki-editin

  7. Comma-separated values - Wikipedia

    en.wikipedia.org/wiki/Comma-separated_values

    Comma-separated values (CSV) is a text file format that uses commas to separate values, and newlines to separate records. A CSV file stores tabular data (numbers and text) in plain text, where each line of the file typically represents one data record.

  8. Nichols plot - Wikipedia

    en.wikipedia.org/wiki/Nichols_plot

    A Nichols plot. The Nichols plot is a plot used in signal processing and control design, named after American engineer Nathaniel B. Nichols. [1] [2] [3] It plots the phase response versus the response magnitude of a transfer function for any given frequency, and as such is useful in characterizing a system's frequency response.

  9. Higher-order programming - Wikipedia

    en.wikipedia.org/wiki/Higher-order_programming

    Higher-order programming is a style of computer programming that uses software components, like functions, modules or objects, as values. It is usually instantiated with, or borrowed from, models of computation such as lambda calculus which make heavy use of higher-order functions. A programming language can be considered higher-order if ...
