Command syntax for matlab function still generates output? -


there two ways call functions in matlab, command syntax , function syntax. viewing code written else in there's statement follows in 1 .m file:

params=sys_params;

while sys_params defined function in .m file as:

function params=sys_params()

params happens structure. wish know is, if according matlab documentation, command syntax cannot used output function, how first statement working well?

two things:

  1. the distinction between command , function syntax comes play when arguments passed.

  2. the parentheses calling function in matlab optional when calling no arguments. matlab call function without invoking () unlike other languages.

    one exception comes mind () required invoke function handle/anonymous function.

from calling functions:

to call function not require inputs , not return outputs, type function name

the 1 ambiguous thing not explicitly told there assigning output of such function call valid.

i'll note don't () optional hides function calls at-first-glance. therefore, try use () possible make clear invoking function, of scripts start clc();clear();.

how use roscolor() ignore value (like empty cell) ? color row if value upper 5 when there nothing in cell, want ignore roscolor() apply, how? public sub roscolor() integer = 0 quotedatagridview1.rows.count() - 1 step +1 dim val integer val = quotedatagridview1.rows(i).cells(3).value if val = vbempty quotedatagridview1.rows(i).defaultcellstyle.backcolor = color.white elseif val < 5 quotedatagridview1.rows(i).defaultcellstyle.backcolor = color.red elseif val > 5 , val < 10 quotedatagridview1.rows(i).defaultcellstyle.backcolor = color.lightyellow end if next end sub you can check empty value following public sub roscolor() integer = 0 quotedatagridview1.rows.count() - 1 step +1 dim val = quotedatagridview1.rows(i).cells(3).value if isdbnull(val) or val nothing quotedatagridview1.rows(i).defaultcellstyle.backcolor = color.white ...

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
