exception handling in matlab - try catch -- MatLab

 exception handling in matlab - try catch -- MatLab When exception occurs, how to handle it? using exception handling keyword try , catch syntax: try      <statement1> catch <exceptionName>      <exception handling statement1> end [NOTE] Great importance. Please pay a lot of attention on it. (1) Unlike C language, there can exist 1 catch block for each 1 exception handling in matlab. (2) Like C language, there can exist nested try , catch , end. (3) UnLike C language, in matlab, if you wanna do different thing according to different exception. You can only determine that in catch block with conditional statement (such as if , switch). more details on: Execute statements and catch resulting errors - MATLAB try catch (mathworks.com)

cospi(x) v.s. cos(pi*x) -- MatLab

   cospi(x) v.s. cos(pi*x) -- MatLab I mentioned the sinpi(x) v.s sin(pi*x) in my article. sinpi(x) v.s. sin(pi*x) -- MatLab (matlabgeeksforgeeks.blogspot.com)  (My article) this has similar to that. cos(x) returns the same result as cos(pi*x) but cospi(x) computes accuracy than cos(pi*x). Because pi in MatLab approximately the pi in math. more details on: Compute cos(X*pi) accurately - MATLAB cospi (mathworks.com)

basic introduction to table in MatLab

basic introduction to table in MatLab [introduction] What is table? A table is a kind of array in tubular form whose name is it column and it can contain elements with different types. How to create a table? keyword table. Type Conversion. Remember that t1->t2 will be represented as <t1>2<t2> array2table  homogenous array to table. cell2table cell array to table. struct2table structure array to table timetable2table timetable to table. table2array table to homogeneous array. table2cell table to cell array. table2struct  table to structure array. table2timetable table to timetable. How to subscript the type? keyword vartype. [syntax] V=vartype(<type>) V will present as <type> e.g. S = vartype( 'numeric' ); T2 = T(:,S) T will converted as numeric type then assign it to the variable T2. How to convert table to a specified type? keyword convertvars or keyword that I mentioned above. [syntax] T2 = convertvars(T1,vars,dataType) will convert the specified...
