The correct way to do the conditions is this: if 0

if FreqSec(1,r+1) > FreqSec(r)*1.01 | FreqSec(1,r+1) FreqSec(r)*1.01 || FreqSec(1,r+1)

if x >= 90 x = A; return else if x >= 80 x = B; return … continue doing this for the other letters too. psd: you need to choose whether 90 will give you an A or a B, and the same goes for all other numbers that are present in two different ranges.

Our coding standards require switch case otherwise blocks over if elseif else blocks everywhere possible for readability. But that's just me

if/elseif/else is quite similar to switch/case/otherwise. Both provide a default action when no conditions are met (else & otherwise) and you're encouraged to use those options. In Matlab, both sets of tests stop execution once a condition is met (in some other languages all cases are executed when there are multiple case matches). I doubt either approach has a computationally efficient beneifit over the other. Here are some of their differences. When there are multple conditions, switch/case/otherwise is often the more organized approach resulting in more readable code. It often reduces the need to use operators and functions to test each condition. For example, when testing string matches, if/elseif/else requires using a string comparson function such as strcmp/i, ismember, etc or an operator (==) for strings while a switch/case/otherwise just uses a string for each case and if case sensitivity should be ignored, the switch statement could use upper/lower to force the sting to upper or lower case while each case-condition contains the same letter-case. switch/case/otherwise is easier to lay out when conditions all rely on the same class such as testing matches to strings, categories,enumerated values but if/elseif/else can be easier to write and read with mixed classes or complex condition tests such as ranges of values. Note that both sets of tests can use expressions or call functions in Matlab but it can become unpleasent to design and read using switch/case/otherwise. Which is more readable for you (ignore that these can likely be vectorized)? % Example 1 country = 'Croatia'; switch lower(country) case 'albania' y = ... case 'bosnia' y = ... case 'croatia' y = ... case 'slovenia' y = ... otherwise error('Country not listed: %s', country) end if strcmpi(country,'Albania') y = ... elseif strcmpi(country,'Bosnia') y = ... elseif strcmpi(country,'Croatia') y = ... elseif strcmpi(country,'Slovenia') y = ... else error('Country not listed: %s', country) end x = pi; switch true case x>0 && x<=1 y = ... case x>1 && x<=2 y = ... case x>2 && x<=3 y = ... case x>3 && x<=4 y = ... otherwise y = . . . end if x>0 && x<=1 y = ... elseif x>1 && x<=2 y = ... elseif x>2 && x<=3 y = ... elseif x>3 && x<=4 y = ... else y = . . . end Also see MATLAB Basics: ‘Switch case’ vs. ‘If elseif’

There is no syntactic sugar for one-line if-statements in MatLab, but if your statement is really simple you could write it in one line.

I used to have one-line if-statements like that in my old project:

if (k < 1); k = 1; end;

In your case it'll look something like:

if a > b; foo = 'r'; else; foo = 'g'; end;

or, if you don't like semicolons

if a > b, foo = 'r'; else, foo = 'g'; end

Not as pretty as you may have expected, though.
