MATLAB Layout Command window (Enter commands directly, view output, give

inputs)

Workspace (Holds all the existing variables created by you while running a program)

Initializing variables v_name = XY will assign memory for a variable named

Variable_name and the value of XY will be stored at that location

d = zeros()

zeros function

Command window commands clc : clears command window

clear v : frees the memory occupied by the variable v

clear all : frees the memory occupied by all variables

Ctrl + C : Terminate program while it is being executed

Math operations (+,-,/,*) + : addition

- : subtraction

/ : division

* : multiplication

Math operations (^,exp,log,log10) ^ : power

exp : exponetial

log : natural logarithm

log10 : logarithm to the base 10

Trignometric functions sin(x) : sine

cos(x) : cosine

tan(x) : tangent

csc(x) : cosecant

sec(x) : secant

cot(x) : cotangent

asin(x) : sine inverse

acos(x) : cosine inverse

atan(x) : tangent inverse

acsc(x) : cosecant inverse

asec(x) : secant inverse

acot(x) : cotangent inverse

Hyberbolic functions

sinh(x) : hyperbolic sine

cosh(x) : hyperbolic cosine

tanh(x) : hyperbolic tangent

csch(x) : hyperbolic cosecant

sech(x) : hyperbolic secant

coth(x) : hyperbolic cotangent

asinh(x) : hyperbolic sine inverse

acosh(x) : hyperbolic cosine inverse

atanh(x) : hyperbolic tangent inverse

acsch(x) : hyperbolic cosecant inverse

asech(x) : hyperbolic secant inverse

acoth(x) : hyperbolic cotangent inverse

Matrix algebra det() : determinant of a square matrix

inv() : inverse of a non-singular square matrix

Matrix algebra Accessing elements of an array, X(i,j) : first index will

denote the row number, second index will denote the column number

Matrix algebra Add, subtract, multiply matrices as simple variables

Creating programs using Editor format for saving of files ____.m

Run programs using Run button

Anything written on a line after % will not be executed

disp() : Used for printing messages and values of variables

Creating programs using Editor input() : used to assign values of variables by user. For string type of

inputs, enter string within single inverted commas fprintf(string,variable_names,) : Used to print strings Use \n for going to next line Use %d for integer type and %f for floating point type, %s for

string type variables

remainder function rem(x,y) : returns the remainder after division of x by

y

(a==b) : a is equal to b

(a~=b) : a is not equal to b

(ab) : a is greater than b

(a=b) : a is greater than or equal to b

Arguments need not be single variables. They can be expressions. E.g. (a

Conditional statements (if-elseif-else-end) if(condition 1)

.statementsend

if(condition 1).statements.else..statements.end

if(condition 1).statementselseif(condition 1)statementsend

Conditional statements (switch-case-otherwise-end) switch expression

case value_1.statements.case value_2.statements.

end

switch expressioncase value_1.statements.case value_2.statements.otherwise.statements.

end

Using loops (for) for i = start_value : step_value : end_value

statements to be repeated..

end

Note : Default step value is 1

while(condition)

..statements to be repeated..

end

Loop will be continuously executed until condition is proven to be false
